Deprecate share email thread (#9319)

## Context

Following this https://github.com/twentyhq/twenty/issues/4199
This has not been fully implemented, after 5months of dead code I'm
removing the feature for the time being until we re-prioritise the
feature (unlikely during these next 6 months) to keep the codebase a bit
cleaner (no need to maintain dead features)

Feel free to reopen / revert this PR once feature is ready

## Test
