Auto merge of #14757 - azdavis:master, r=lnicola

Fix libs publish branch filter

line-index didn't actually get published from #14733, probably because the branch filter was for main but the main branch is called master here. This fixes the workflow file

I also tweaked the libs readme mostly just so the paths filter would pick up the changes.
