feat: Add unit test to verify that every Notice has an entry in RULES.md

[bdferris-v2]

Summary:

When writing new validation rules, we often forget to update RULES.md with updated documentation. While #1324 has some ideas on addressing that in the long term, in the short term, we can add a unit-test that will fail if there is an entry in RULES.md for a newly added notice.

For example, this test should fail initially because StopWithoutLocationNotice is missing from RULES.md per #1330.

Thank you for adding this test @bdferris-v2 !

unit-test that will fail if there is an entry in RULES.md for a newly added notice.
You mean that will fail if there is no entry in RULES.md for a newly added notice, right?

Why is the test_pack_doc workflow failing in this PR?

[bdferris-v2]

@isabelle-dr the test is correctly identifying that StopWithoutLocationNotice is not properly documented in RULES.md and failing as result :)
