Tags property causes case sensitive Env tag to fail

[BernieWhite]

Description of the issue

When resource specifies tags they must be defined under the Tags (case-sensitive) property or the CAF.Tag.Environment rule will fail. Case sensitivity should only apply to the tag i.e. Env not the tags property name.

Expected behaviour

The resource Tags property should not be case-sensitive but the tag under the Tags property should be.
