Updating golang-github-charmbracelet-glamour, golang-github-muesli-gitcha, golang-github-caarlos0-env

Hi Aloïs and Anthony!

I know the packages are team maintained, but just to be sure I wanted
to check if you are OK if I update the mentioned packages to latest
version, ask for review on this list and then upload to unstable? I
already did test imports and reverse dep builds in my fork so I know
it is doable.

I need newer versions of these for Glow (ITP Bug#1088206).

Also, can I have admin permissions to the repos so I can modernize
them and have Salsa CI properly enabled?

Thanks!
