git rev-list --tags --max-count=1 can return older tags first

[martinsbalodis]

From git docs the git rev-list command returns commits in "reverse chronological order". After doing some git rebaseing I got into a situation where this command didn't return the latest tag but instead returned one before. As a result the action tried to create a tag that already existed.

This could be fixed by changing:

git rev-list --tags --max-count=1

to:

git rev-list --tags --topo-order --max-count=1

Ah weird. Do you want to send a PR?
