Compile with swc on twenty-server (#4863)

Experiment using swc instead of tsc (as we did the switch on
twenty-front)

It's **much** faster (at least 5x) but has stricter requirements.
I fixed the build but there's still an error while starting the server,
opening this PR for discussion.

Checkout the branch and try `nx build:swc twenty-server`
