Centralize Ecosystem CI results somewhere (or be alerted of failures)

As discussed with danblack, one of the Ecosystem CI strategy is to ask directly upstream to test against MariaDB. See: https://github.com/grooverdan/wordpress-develop/commit/8a2079fa2bc3f9ea27a0d1016d5c8f9a2e1c6369

The purpose of this MDBF is to find a solution to be alerted if Upstream Ecosystem CI have failure.

First suggestion/idea:
Create a page on BB that will centralize all the CI badges.
