Getting latest tag in `extra-packages` not working correctly

[rchl]

extra-packages allows fetching latest tag of specified package by either not specifying ref or specifying just a tag prefix.

With:

          extra-packages: sublimelsp/LSP@4070-

it fails to sort the tags properly and returns some old one. Checked with equivalent code in terminal:

git ls-remote --tags --heads https://github.com/sublimelsp/LSP | sed -E -n "s%.*refs/tags/(4070-[0-9]+\.[0-9]+\.[0-9]+)\$%\1%p" | grep -v '\^{}$' | sort -t. -k1,1nr -k2,2nr -k3,3nr | head -n1
4070-1.30.0

I think it would need to strip the prefix (4070- in this case or v in some other cases) before sorting. Otherwise it's not sorted correctly. But then the original prefix would have to be also included when returning result.

Relevant code:
