deps: github.com/aws/aws-sdk-go@v1.30.12 [master] (#24745)

* update github.com/aws/aws-sdk-go to v1.30.9

* deps: github.com/aws/aws-sdk-go@v1.30.12

Reference: https://github.com/hashicorp/terraform/issues/24710
Reference: https://github.com/hashicorp/terraform/issues/24741

Changes:

```
NOTES:

* backend/s3: Region validation now automatically supports the new `af-south-1` (Africa (Cape Town)) region. For AWS operations to work in the new region, the region must be explicitly enabled as outlined in the [AWS Documentation](https://docs.aws.amazon.com/general/latest/gr/rande-manage.html#rande-manage-enable). When the region is not enabled, the Terraform S3 Backend will return errors during credential validation (e.g. `error validating provider credentials: error calling sts:GetCallerIdentity: InvalidClientTokenId: The security token included in the request is invalid`).

ENHANCEMENTS:

* backend/s3: Support automatic region validation for `af-south-1`
```

Updated via:

```console
$ go get github.com/aws/aws-sdk-go@v1.30.12
$ go mod tidy
$ go mod vendor
```

-See http://jmespath.org for more info.
+go-jmespath is a GO implementation of JMESPath,
+which is a query language for JSON.  It will take a JSON
+document and transform it into another JSON document
+through a JMESPath expression.
+
+Using go-jmespath is really easy.  There's a single function
+you use, `jmespath.search`:
+
+
+```go
+> import "github.com/jmespath/go-jmespath"
+>
+> var jsondata = []byte(`{"foo": {"bar": {"baz": [0, 1, 2, 3, 4]}}}`) // your data
+> var data interface{}
+> err := json.Unmarshal(jsondata, &data)
+> result, err := jmespath.Search("foo.bar.baz[2]", data)
+result = 2
+```
+
+In the example we gave the ``search`` function input data of
+`{"foo": {"bar": {"baz": [0, 1, 2, 3, 4]}}}` as well as the JMESPath
+expression `foo.bar.baz[2]`, and the `search` function evaluated
+the expression against the input data to produce the result ``2``.
+
+The JMESPath language can do a lot more than select an element
+from a list.  Here are a few more examples:
+
+```go
+> var jsondata = []byte(`{"foo": {"bar": {"baz": [0, 1, 2, 3, 4]}}}`) // your data
+> var data interface{}
+> err := json.Unmarshal(jsondata, &data)
+> result, err := jmespath.search("foo.bar", data)
+result = { "baz": [ 0, 1, 2, 3, 4 ] }
+
+
+> var jsondata  = []byte(`{"foo": [{"first": "a", "last": "b"},
+                           {"first": "c", "last": "d"}]}`) // your data
+> var data interface{}
+> err := json.Unmarshal(jsondata, &data)
+> result, err := jmespath.search({"foo[*].first", data)
+result [ 'a', 'c' ]
+
+
+> var jsondata = []byte(`{"foo": [{"age": 20}, {"age": 25},
+                           {"age": 30}, {"age": 35},
+                           {"age": 40}]}`) // your data
+> var data interface{}
+> err := json.Unmarshal(jsondata, &data)
+> result, err := jmespath.search("foo[?age > `30`]")
+result = [ { age: 35 }, { age: 40 } ]
+```
+
+You can also pre-compile your query. This is usefull if 
+you are going to run multiple searches with it:
+
+```go
+	> var jsondata = []byte(`{"foo": "bar"}`)
+	> var data interface{}
+    > err := json.Unmarshal(jsondata, &data)
+	> precompiled, err := Compile("foo")
+	> if err != nil{
+    >   // ... handle the error
+    > }
+    > result, err := precompiled.Search(data)
+	result = "bar"
+```
+
+## More Resources
+
+The example above only show a small amount of what
+a JMESPath expression can do.  If you want to take a
+tour of the language, the *best* place to go is the
+[JMESPath Tutorial](http://jmespath.org/tutorial.html).
+
+One of the best things about JMESPath is that it is
+implemented in many different programming languages including
+python, ruby, php, lua, etc.  To see a complete list of libraries,
+check out the [JMESPath libraries page](http://jmespath.org/libraries.html).
+
+And finally, the full JMESPath specification can be found
+on the [JMESPath site](http://jmespath.org/specification.html).
