Prepare web for 8.0.0 release

[JammingBen]

The upcoming OC rolling release will include the next Web major jump to v8.0.0.

We need to:

• Check for @deprecated flags, remove and document them. We should verify each finding if it can safely be removed, or if we should keep it deprecated a bit longer.
• Remove @sentry/vue
• If time in the sprint permits, we still have backlog items waiting for major releases:
  • Move more actions to files app: Move remaining file actions from web-pkg to web-app-files #2470
  • Remove custom size types [design-system] Replace custom size type with tailwind classes #2820
