error when deleting inconsistent tag

[proppy]

Currently conda-build-prepare relies on git describe to get the latest reachable tag: https://github.com/hdl/conda-build-prepare/blob/master/conda_build_prepare/git_helpers.py#L235

This can lead to the following Traceback when the repo has inconsistent tags:

2022-12-21T12:52:21.9200403Z error: tag 'Public_Release-7.6.0-77-g50daf8e8e069363aea2fe91cc8012a8d3038bd87' not found.

This is due to a git-describe "feature" (described in https://patchwork.kernel.org/project/git/patch/fcf19a46b80322c5579142efe4ec681a4dcbdd28.1581802264.git.matheus.bernardino@usp.br/) which attempt to resolve inconsistent tags:

Xyce 🍙 git describe --tags --abbrev=0
warning: tag 'Release-7.6.0' is externally known as 'Public_Release-7.6.0'
Public_Release-7.6.0-77-g50daf8e8e069363aea2fe91cc8012a8d3038bd87

We should find a more reliable way to extract the latest reachable tag.
