I'm getting flagged for unexpected markdown file, but the file its flagged is `readme.md`. https://playground.wordpress.net/?blueprint-url=https%3A%2F%2Fwordpress.org%2Fplugins%2Fwp-json%2Fplugins%2Fv1%2Fplugin%2Frunthings-taxonomy-template-selector%2Fblueprint.json%3Fzip_hash%3D99e4cae077a648f31b6aee1b16751737%26type%3Dpcp According to this code, README.md and its lowercase equivalent should be allowed? https://github.com/WordPress/plugin-check/blob/bb4326d217b85fa1a638d8e4f0bf85799f145b73/includes/Checker/Checks/Plugin_Repo/File_Type_Check.php#L572
