[PATCH 0/3] doc: txt -> adoc fixes

I noticed broken links in the howto-index.html output of v2.49.0-rc0. This is due to the recent txt -> adoc renaming. I chose to replace the numerous occurences of "txt" with "adoc" in howto-index.sh for consistency within the script. It could be argued that only the few instances which glob '*.txt' should be changed, of course.

I also renamed the git-*.txt files in contrib/contacts and contrib/subtree while I was here. The only other file in contrib which might warrant that treatment is contrib/mw-to-git/git-remote-mediawiki.txt. I skipped it as I am not sure whether it is actively maintained anymore. If we want to rename it to be consistent, that's easy enough.
