As of this commit, that layout doesn't exist yet, but I'm isolating the one-line
changes to their own commit to try and keep your eyes from glazing over.
* Make sidebar nav in language docs more intuitive
* Minor display fixes for registry docs
* Explain providers in the registry in the providers index
* Revise a bunch of language docs around provider reqs
This is mostly an effort to smooth out some of the explanations, make sure
things are presented in a helpful order, make sure terminology lines up, draw
connections between related concepts, make default behavior more apparent, and
the like. It shouldn't include very much new information, but there might be one
or two things that came out of a conversation somewhere.

The "Configuration Language" section was becoming rather unweildy, both
by having a lot of pages and by some of the pages being quite large in
themselves.
This is a first step towards breaking things up a little more, starting
with two changes:
- The "Configuration Language" navigation is now split into two
sub-headings "Configuration Blocks" and "Syntax".
- Some of the information about sub-blocks of the "terraform" block are
now given their own pages, because their content is quite complex
in itself.
- "Version Constraints" is now a page in its own right, rather than this
content being duplicated in slightly different forms across multiple
contexts that make use of user-specified version constraints.
Implement a new provider_meta block in the terraform block of modules, allowing provider-keyed metadata to be communicated from HCL to provider binaries.
Bundled in this change for minimal protocol version bumping is the addition of markdown support for attribute descriptions and the ability to indicate when an attribute is deprecated, so this information can be shown in the schema dump.

The existing "type" argument allows specifying a type constraint that
allows for some basic validation, but often there are more constraints on
a variable value than just its type.
This new feature (requiring an experiment opt-in for now, while we refine
it) allows specifying arbitrary validation rules for any variable which
can then cause custom error messages to be returned when a caller provides
an inappropriate value.
variable "example" {
validation {
condition = var.example != "nope"
error_message = "Example value must not be \"nope\"."
}
}
The core parts of this are designed to do as little new work as possible
when no validations are specified, and thus the main new checking codepath
here can therefore only run when the experiment is enabled in order to
permit having validations.
This commit is a wide-ranging set of edits to the pages under
/docs/configuration. Among other things, it
- Separates style conventions out into their own page.
- Separates type constraints and conversion info into their own page.
- Conflates similar complex types a little more freely, since the distinction is
only relevant when restricting inputs for a reusable module or resource.
- Clarifies several concepts that confused me during edits.
As part of revamping the "Configuration" portion of the website for the
v0.12 release, here we update the Terraform Settings page to use a similar
"guide-like" writing style as the other updated pages in this section.
