PERF203 should only trigger if loop control flow isn't in the try block

[evanrittenhouse]

Copied from #4789 (comment):

PERF203 should only trigger when there’s no loop flow control (break, continue) in the try-catch statement. E.g. I don’t think there’s a better way to write the following:

for repo in ['R-patched', 'cran', 'bioc']:
    try:
        pkg_cache = self._fetch_cache(repo, pkg)
        break
    except HTTPError:
        pass
else:
    return None

I just find that this false positive still exists, but only on certain target-version.

it pass with target-version = 'py311' but failed with target-version = 'py38'
