Exceptions from Tokenserver's verify.py should emit Sentry events

[data-sync-user]

During a recent FxA outage there were exceptions raised by the Python verify code that would show up in logs, but not sentry, e.g.

fxa.errors.OutOfProtocolError: API responded with non-json content-type: text/html

raise fxa.errors.OutOfProtocolError(msg.format(content_type))

File "/usr/local/lib/python3.11/dist-packages/fxa/_utils.py", line 273, in request

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

return self.request("POST", url, json, **kwds)

File "/usr/local/lib/python3.11/dist-packages/fxa/_utils.py", line 341, in post

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

resp = self.apiclient.post('/verify', {'token': token})

Traceback (most recent call last):
File "verify.py", line 14, in verify_token
File "/usr/local/lib/python3.11/dist-packages/fxa/oauth.py", line 280, in verify_token

(pulled from BigQuery so it might be a bit jumbled).

For ease of diagnosing issues, such errors (those not explicitly caught in verify.py) should also be logged as Sentry events.
