This changes allows the consumer to restrict polymorphic linting to specified components.
Linting components may raise false positives when a component handles behavior that the linter has no way to know.

This means that linting components is preferred on very basic utility components.

This change adds support for eslint v9. All three example projects have been updated to use the latest eslint, and the root package's dev and peer deps have been updated.

In order to make this work with both v9 and older versions, I had to update the parser options helper to adjust the config passed into the `RuleTester`.

Fixes #966

The rule no longer errors if the existence of label text cannot be determined

Fixes #1005 by introducing a second error message, used when the label
doesn't have accessible text.

This allows us to:
 - drop all the jest mocks
 - no longer be stuck on an EOL version nor be forced to raise the engines.node threshold
 - run tests 4x faster: jest takes 27.365s, tape takes 7.086s
