Remove stale branches

[satorg]

Hello everyone.
I did some repository cleanup – namely, removed many of stale branches gathered in the repo.
Most of them were those already merged from typelevel-steward.

Also some of the deleted branches were very old ones that didn't receive any updates for 6 years or more with names like 1.11.x, 1.12.x, etc. The corresponding release tags are kept intact, of course, but I feel there are close to zero chances that such an old lines will ever get any maintenance. We can always spawn a new branch out of the corresponding release tag, if necessary.

However, there are still some old branches that I am not confident about:

Branch	Updated	Behind	Ahead
1.14.0_sonatype	5 years ago	1039	10
1.14.x	4 years ago	825	29
1.15.2_sonatype	3 years ago	562	1

I'm not really sure whether we should keep or drop them.

There's no need for immediate action – I'd just like to keep this issue for a while and collect all the opinions.
However, if someone has any opinion on those branches, leave a comment about it please at your convenience.

Also, even though I tried hard to avoid losing any potentially important branches, but since there were dozens and dozens of them, some such branches might have passed unnoticed. So I would appreciate if everyone who cares could check if there's anything important missing in the repo.

Thank you everyone!

• 1.14.0_sonatype: the substantial commits are already on main
• 1.14.x: the substantial commits are already on main
• 1.15.2_sonatype: the latest 1.15.x is already on scala-native-0.4

I think they can all be safely cleaned up.
