Subject: [PATCH] chore(sentry): decrease tracesSampleRate to prevent blowing
 through quota (#44901)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Chore

## What is the current behavior?

100% of traces are being sent to Sentry, which alone would blew through
all of our quota leaving no spans available for other projects. For
April we are already rate limited.

## What is the new behavior?

Change `tracesSampleRate` to more reasonable value (0.02).
