Update for WordPress 6.9 compatibility and CI matrix

Verified compatibility with WordPress 6.9 and updated the CI test matrix to include WordPress 6.9, 6.8, and 6.7 (removing 6.5 and 6.6). Updated development dependencies: mockery/mockery to ^1.6 and wp-graphql/wp-graphql-testcase to ^3.4. Removed GitHub Plugin URI and Update URI headers for WordPress.org compatibility and reduced readme.txt tags to five for compliance. Updated .wp-env.json to use the latest WordPress core. Refreshed composer dependencies, including a major update to lucatume/wp-browser and related packages.
