Ticket CI

[vbraun]

The aim of this ticket is to:

• add CI that runs on each ticket (using github actions)
• use self-hosted runner that is fast enough to build all tickets from scratch
• prevents tickets from being merged unless it succeeds
• add status badge to trac

The code from trac ticket will be pushed by an external script to a branch ticket/12345, and this will trigger the CI run.

Example runs: https://github.com/vbraun/sage/actions/workflows/ticket.yaml

Component: build

Just as a heads-up: something similar is done in #33263 (already ready for merge)

+1 on providing fast self-hosted runners if you have them

-1 on designing workflows that only can succeed on self-hosted runners

(I haven't looked at the yml)
