[Debian-salsa-ci] Added Jochen as 'Maintainer' in Salsa CI

[Otto Kekäläinen]

Hi!

Based on top contributors in past year and with emphasize on recent
activity, I decided to add Jochen as 'Maintainer' at
https://salsa.debian.org/groups/salsa-ci-team/-/group_members

It is very nice that we have a lot of contributions and MRs, but it
puts a lot of strain on only a handful of current core contributors to
review and merge everything. With this change we have more people who
can also merge MRs. I trust you to be diligent in what gets merged.

Note that already from before, a way larger group of people can add
their Approve to MRs, and anyone with a Salsa account can "thumbs up"
and comment MRs to help us prioritize and get MRs reviewed and merged
faster.

This is in line with how new Maintainers were added in 2025
(https://alioth-lists.debian.net/pipermail/debian-salsa-ci/2025-September/000312.html).
