Re-enable Sentry client reports after updating to Sentry 10.34.0

[lognaturel]

@alxndrsn filed getsentry/sentry-javascript#18802 (comment) upstream and a fix was released in 10.34.0

We'll then be able to undo the change at https://github.com/getodk/central-backend/pull/1729/changes

Assigning to @ktuite because hopefully this will be quick to do after she updates Backend dependencies.
