docs: https://bazel.build/concepts/dependencies still refers to old style directory labels

[uri-canva]

Description of the feature request:

https://bazel.build/concepts/dependencies#using-labels-reference-directories (and its pre-move equivalent https://docs.bazel.build/versions/main/build-ref.html#label_directory) still refer to labels pointing to directories with the old syntax like data = ["testdata/."], mentioning them being present in the bazel source code. As far as I can tell there are no such references in the bazel codebase anymore. In addition to that since https://github.com/bazelbuild/bazel/issues/1025 has been solved directories should now be able to be referred to with the regular label syntax as if they were files.

The documentation as is makes it confusing as it implies labels referring to directories need to use that outdated syntax and have caveats which I don't think are true anymore.
