New list: tpa-team
as part of #31242 (closed) (which is to reduce the noise TPA users receive), it seems we still need a place for discussions, after everything is moved off to their rightful place.
a list alias works, but because it's so hard to keep it silent, it seems better to create a separate forum where more users, which do not need to see all that traffic, can join and participate.
this is especially important now that we have folded the web team inside TPA.
