docs: remove incorrect watchPlugins: false references

Remove all references to the incorrect `config.watchPlugins: false`
requirement that was believed necessary for Headlamp v0.39.0+.

Investigation revealed that plugins work correctly with the default
`watchPlugins: true` setting. The earlier documentation was based on
a misunderstanding of the plugin loading mechanism.

Changes:
- Remove watchPlugins: false from all YAML configuration examples
- Remove warning sections about watchPlugins requirement
- Update troubleshooting guides to focus on actual issues
- Simplify installation instructions by removing unnecessary config

Files updated:
- README.md (main installation docs and troubleshooting table)
- docs/DEPLOYMENT.md
- docs/TROUBLESHOOTING.md
- docs/getting-started/* (quick-start, installation, prerequisites)
- docs/deployment/* (helm, production)
- docs/troubleshooting/* (common-issues, README)
- Multiple other doc files formatted by prettier

This cleanup ensures ArtifactHub and GitHub documentation show
correct, simplified installation instructions.
