main/readline: upgrade to 8.2.7
https://git.savannah.gnu.org/cgit/readline.git/log/
I have also imported a patch from Debian to fix https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1056314 (i downloaded the CI build artifacts, and confirmed that the patched libreadline
no longer crashes bash and sqlite3).
