fix(replay): fix feedback replay context not resetting (#98757)

https://linear.app/getsentry/issue/REPLAY-129/replay-previewer-buggy-when-viewing-a-played-video

Fixes the issue where the `currentTime` was getting mutated when
navigating between different feedback replay previews.

This change will force the entire lazy-loaded component tree (including
the `ReplayContextProvider`) to completely re-mount whenever the
`replayId` changes. This includes resetting the `ReplayContextProvider`
state, which contains the `currentTime` that was getting corrupted.
