[Debian-salsa-ci] More Salsa CI stats

[Otto Kekäläinen]

Hi!

Lucas just published a new version of trends.debian.net, and now it
also includes:

https://trends.debian.net/#continuous-integration-on-salsa

Now with both this and salsa-stats.debian.net we could perhaps plan
some campaign to drive adoption (activate salsa-ci.yml in all
packages) or best practices (disable salsa-ci.yml or individual jobs
if they don't pass).
