simplifies release retrieval using git tags

[nverno]

This is a simple alternative to retreive releases from the git mirror as the previous list-all command seems to be broken. It seems better to avoid sorting as well, since git tags will be chronological.

Hello, thanks for your PR! could you rebase on master and just confirm it works for you ? Thanks !

Hi, this was a simplified alternative to the pull request that was just merged. I don't know if you want to use curl + sorting or git tags?

Oh right, I guess using git tags is better. Please update this PR and I'll merge, just make sure the newest version is at the end of list-all output. IIRC, this line installs the last version in output.
