Use a slightly modified value renderer from terraform-provider-testing
to display values in the console REPL, as well as outputs from the apply
and outputs subcommands.

Note that this is technically a breaking change for the console
subcommand, which would previously error if the user attempted to render
an unknown value (such as an unset variable). This was marked as an
unintentional side effect, with the goal being the new behaviour of
rendering "(unknown)", which is why I changed the behaviour in this
commit.
