GHSA Add unaffected_versions to CVE-2024-27456

[Cdestewart]

Updated the advisory for CVE-2024-27456 to include the unaffected versions.

[Kilomaster3]

@postmodern could you please check this PR?

[jlw]

From my reading of cyu/rack-cors#274 this change is also not correct. The unaffected versions should be everything before 2.0.1 - v 2.0.0 should not be counted as affected.

[postmodern]

Manually confirmed that only rack-cors 2.0.1 is effected.

$ gem fetch rack-cors -v 2.0.0
$ tar xvf rack-cors-2.0.0.gem
$ tar tzvf data.tar.gz
