Bug 33183: Error inserting matchpoint_components when creating record matching rules with MariaDB 10.6

The word "offset" is now a keyword. At the very least we need to escape the fieldname with backticks.
It would be nice to switch to Koha::Objects for this module eventually.

C4::Matcher::_store_matchpoint(): DBI Exception: DBD::mysql::st execute failed: You have an error in
your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax
to use near 'offset, length) VALUES ('27', '1', '999'...' at line 2 at /usr/share/koha/lib/C4/Matcher.pm
line 314

Test Plan:
1) Set up Koha with MariaDB 10.6
2) Attempt to create a matching rule
3) Note the error screen
4) Apply this patch
5) Restart all the things!
6) Attempt to create another matching rule
7) No errors this time
