Delete excluded rules for duplicate-id and duplicate-id-active from the component guide accessibility tests

What

Delete the excluded rules for duplicate-id and duplicate-id-active from the component guide accessibility tests.

Why

The 4.8 release of Axe Core deprecated the duplicate-id and duplicate-id-active rule, along with setting the duplicate-id-aria to always report as "needs review" rather than as a violation.

...Axe-core currently has three rules to test success criterion 4.1.1 Parsing. All three of these are related to duplicate IDs

For WCAG 2.2 criterion 4.1.1 Parsing is removed.
