Skip checking style tags, SVGs and media.

Code Review

This pull request introduces improved logic for the attr-value-no-duplication rule, specifically by skipping SVG elements and style attributes, and adding special parsing for media attributes. A critical issue was found where media attributes are unintentionally skipped before their new parsing logic can be applied. A minor suggestion was made to clarify a test description related to media attributes. Once the primary issue is addressed, the changes should correctly enhance the rule's behavior.
