Spike - next.js investigation

[kmcfaul]

• Figure out the lift if we want to transition from Astro to Next.js
• Determine if Next.js is more compatible with Patternfly expected architecture / DOM structure. Especially regards to page structure / sidebar & page performance
• POC

Currently, the migration to next js would be a heavy lift. It is moving to turbo pack which is in contrast to our current move towards vite. There is no support for CLI that we currently have access when using astro.
