Map shapes (string -> string) are already a valid representation for tags in TagResource/ListTagsForResource per verifyTagsShape, but the member-name regex only accepted Tags/TagList variants. Loosen the TAG_PROPERTY_REGEX to also accept TagMap/tagMap/TagsMap/tagsMap (and case variants), aligning name validation with the shape validation that already supports maps.

Background
Map shapes (string -> string) are already a valid representation for tags in TagResource/ListTagsForResource per verifyTagsShape, but the member-name regex only accepted Tags/TagList variants. Loosen the TAG_PROPERTY_REGEX to also accept TagMap/tagMap/TagsMap/tagsMap (and case variants), aligning name validation with the shape validation that already supports maps.
Services that may use the map shape for their tags may want to align the member names with that type for internal consistency in their API fields.
Testing
Ran all existing tests and added valid tagMembers test case.
