Replace deprecated sentry_sdk call

[jimchamp]

Background

The sentry_sdk.push_scope function has been deprecated and is slated for removal in the next major version. It's unclear when version 3.0 of the SDK will be released, but it is being worked on now.

Sentry documentation offers guidance for replacing push_scope calls, here.

Open Library calls sentry_sdk.push_scope here:

openlibrary/openlibrary/utils/sentry.py

Lines 85 to 93 in 4ff15b7

	def capture_exception_webpy(self):
	with sentry_sdk.push_scope() as scope:
	scope.add_event_processor(add_web_ctx_to_event)
	sentry_sdk.capture_exception()
	def capture_exception(self, ex):
	with sentry_sdk.push_scope() as scope:
	scope.add_event_processor(add_web_ctx_to_event)
	sentry_sdk.capture_exception(ex)
