fix(integrations): Prevent ApiInvalidRequestError from creating Sentry issues

[sentry]

This PR addresses an issue where ApiInvalidRequestError exceptions, specifically those originating from the integration proxy returning a 400 Bad Request during GitHub get_rate_limit calls, were being captured as Sentry issues.

The SCMIntegrationInteractionEvent context manager, used in get_rate_limit, was configured to call record_failure(create_issue=True) for any unhandled exception. However, the _populate_trees function, which calls get_remaining_api_requests (which in turn calls get_rate_limit), already gracefully handles these exceptions by falling back to a cache.

To prevent excessive Sentry issue noise from these known and handled conditions, this change modifies IntegrationEventLifecycle.__exit__ to treat ApiInvalidRequestError as a halt rather than a failure. This mirrors the existing handling for RestrictedIPAddress exceptions. The event is still recorded as a halt in SLO metrics, ensuring visibility without generating unnecessary Sentry issues.

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Fixes SENTRY-5JQ5
