CONSOLE-5100: Remove support for PatternFly 5

[logonoff]

Future releases of PatternFly will include a theme which will look better if all components use PatternFly 6 components.

In the next version of OpenShift we aim to adopt this release of PatternFly, we should drop PatternFly 5 as preparation.

Summary by CodeRabbit

• Chores
  • Removed all PatternFly 5 package dependencies, CSS imports, and styling definitions from the application
  • Cleaned up legacy PatternFly 5 SCSS styling overrides and ancillary styling configurations
  • Updated application build configuration and dependency validation checks to support only PatternFly 6
  • Removed all remaining PatternFly 5 references from webpack configuration and npm packaging setup

📝 Walkthrough

Walkthrough

This pull request removes PatternFly 5.x support across the frontend, consolidating the codebase to PatternFly 6.x exclusively. Changes include removing the PatternFly 5 npm alias from package.json dependencies, deleting ancillary PF5 SCSS styling (448 lines of variable mappings and form-control overrides), removing PF5 style imports from the main stylesheet and webpack entry point, updating release notes to document the removal, and eliminating PatternFly v5 from the module validation script. The consolidation streamlines the build configuration and reduces CSS complexity.
