Don't use the minimised width(68px) on the new room list (#29778)

* Don't toggle to the minimised left bar size.

* Don't re-style old room list when at the minimum size

* Only apply larger minimised with on new room list

* Don't tell child views we are minimised for the new room list

* move comment to the correct place

* address PR comments

* Don't wrap search text and add truncation down to a minimum of 50px

* Put min-width on the button so that we don't have to hardcode the 50px

* Keep the flex display, shrink and truncate just the search text and keep the shortcut

* Update snapshots

* Add comment for magic value

* Make inner search text a span

* Add e2e test for smallscreen to test responsiveness

* Update snapshots

* Forcing an empty commit to fix PR

* Change minWidth to 224
