Consider lightweight tags in GixBuilder::describe() based on tags

[SanchithHegde]

This PR updates the vergen-gix crate to consider lightweight tags in a git repository when emitting the describe output, depending on the value of the tags parameter provided. This fixes the issue reported in #359 (comment). This PR also updates the test repo creation code to create a lightweight tag, and adds a test case in the vergen-gix crate.

While working on this PR, I noticed that the vergen-gix crate does not consider the matches parameter, I've opened #363 so that it's documented for other users of the crate.

@CraZySacX Should I worry about the failing code coverage tests? I don't see any commands being run for the code coverage step, since the configuration variable being read in the workflow file (VERGEN_RUN_CMD) is not available in my fork.

No, it's not your fault. I moved to re-usable workflows to support all of my rust projects and they don't allow forks to read environment variables. The coverage workflow depends on a couple and fails in forks because they are empty. I'm still trying to figure out the best way to handle it.

@CraZySacX If it isn't asking for too much, could you please release vergen-gix v1.0.1 with this fix? We were thinking of migrating one of our repos from vergen-git2 to vergen-gix, and describe is the only aspect where the output of vergen-gix differs.

Yep, will get this out today.
