add warning when module version is not 0.0.0

[AlexanderLanin]

version in MODULE.bazel files must either match the tag exactly or be set to 0.0.0.
Everything else is just confusing.
Add a warning.

Note: some explicitly define 0.0.0 as the local versions. Others do not define a version at all.
example: https://github.com/bazelbuild/apple_support/blob/main/MODULE.bazel

Do we need to write a version??
