This way we can have a task to immediately destroy a repo, and it
clarifies what the task does.

We want an "immediate" job because we do want to trash some repos and
there might be some checks to do then.

Closes: team#41474

The previous page was standalone, not linked from anywhere, so really
hard to find. It also seems to me small enough that it can fit in
another page. We don't have docs specifically for donate, so let's
cram this in the CRM docs.

This will make further updates easier, as we won't have to patch
previous versions by hand like we just did.

This will make the output more readable, at the cost of making the
directives slightly less readable.

otherwise we show the old kernel that's about to be removed anyway.
