Remove old pre-join UTD logic (#12464)
* remove old pre-join UTD logic and add a playwright test for new pre-join UTD * remove variable that isn't used any more * add missing synapse template * remove unused variable (again) and run prettier * add test that we can jump to an event before our latest join membership event * modify default template instead of creating a new template
