Bug - eslint-plugin-patternfly-react - not compatible with Eslint 9

[dlabrecq]

Describe the problem The eslint-plugin-patternfly-react plugin is not compatible with Eslint 9.

API changes were announced in september 2023 and eslint v9.0.0 is available as of a couple weeks ago.

Additionally, there are some rule structure changes outlined separately that may be worth ensuring are in compliance.

How do you reproduce the problem?

1. Upgrade to Eslint 9
2. Tests should fail

Expected behavior Eslint 9 should work with this plugin
