Bitnami legacy images are not automatically detected

[mhalbritter]

The changes from Bitnami are now partially live.

// Edit: It appears they brownout some images instead of switching them off all at once. But we need to do something regardless.

We have to adapt our tests, maybe to use the Bitnami legacy images?

We're going to remove Bitnami support in main. In 3.4.x and 3.5.x, we will only test against the legacy images having updated the connection details factories to look for the new Bitnami coordinates. We will keep (untested) support for the old coordinates to maintain backwards compatibility as best we can in 3.x.

I've opened #47267 to remove support in 4.0.
