Sort pyenv tags as versions

[Hellzed]

What changes are proposed in this pull request?

By default, git ls-remote command sorts its output lexicographically, this causes pyenv 2.3.9 to be considered the latest version even if 2.3.17 is available.
Treating git tags as semver strings (where 2.3.17 > 2.3.9) fixes this behavior.

This fixes mlflow models build-docker not working for recent Python versions only available with newer pyenv releases.

How is this patch tested?

• Existing unit/integration tests
• New unit/integration tests
• Manual tests (describe details, including test results, below)

Trying to build a model logged with Python 3.11.3 consistently fails without this patch, with the error:

python-build: definition not found: 3.11.3
