Thread: pgcommitfest2: Remove trailing slashes from message-id URLs

This archive links from the commit fest app are like

    https://www.postgresql.org/message-id/flat/BLAH/

which is redirected to

    https://www.postgresql.org/message-id/flat/BLAH

So it seems like the links shouldn't include the trailing slash in the
first place.

See attached patch.
