Handle beta version not yet updated in product-details

[DonalMe]

For a few days after each release, product-details still reports the old beta version (e.g. release=149, beta=149, nightly=150) because no Fx150 beta builds have landed yet. This caused get_checked_versions() to fail its consecutive-version check and return {}, silently disabling the regression_set_status_flags rule for that window. This has always been a problem, but the window is longer since we don't ship beta until a few days after merge day.

When release == beta and nightly == release + 1, we now treat beta as nightly (N+1) so the rule can continue running.

This is a naive fix, but it might help re-evaluate this logic.

Pull request overview

Adjusts get_checked_versions() to keep Bugbot’s version-dependent rules running during the post-release window where product-details reports a stale beta version.

Changes:

• Detect the release == beta and nightly == release + 1 “stale beta” scenario from product-details.
• Treat beta as nightly (N+1) for this window and return the adjusted versions map (instead of returning {}).

In this special-case branch you return versions without re-checking that product-details nightly (v[2]) matches the nightly version inferred from Bugzilla (the validation done in the consecutive-versions branch). If Bugzilla has already advanced but product-details is still stale, this will re-enable rules with inconsistent version data. Consider running the same Bugzilla mismatch check here (and returning {} on mismatch) before returning the adjusted versions.

Suggested change

	versions["beta"] = str(v[2])
	versions["beta"] = str(v[2])
	nightly_bugzilla = get_nightly_version_from_bz()
	if v[2] != nightly_bugzilla:
	logger.info("Versions mismatch between Bugzilla and product-details")
	return {}
