Restrict SIM105 to try blocks with a body of one simple statement

[andersk]

If a try block has multiple statements, a compound statement, or control flow, rewriting it with contextlib.suppress would obfuscate the fact that the exception still short-circuits further statements in the block.

Fixes #1947.

Could you give an example of how contextlib.suppress would obfuscate this?

I gave an example in #1947.

for i in range(1, 100):
    try:
        realm.string_id = prefix + str(i)
        realm.save(update_fields=["string_id"])
        break
    except IntegrityError:
        pass
else:
    raise RuntimeError(f"Unable to find a good string_id for realm {realm}")

Ah, my bad I didn't see the issue. Thanks.
