feat(docs): migrate from AWS Amplify to GitHub Pages deployment (#5)

* feat(docs): add Amplify redirects for /hub/ subpath

Add _redirects file to handle Amplify routing for Docusaurus site served at /hub/ path

* fix(docs): configure rewrites for /hub/ subdirectory deployment

- Update _redirects file with proper asset rewrite rules for AWS Amplify
- Add security headers to amplify.yml
- Ensure asset paths (/hub/assets/*) are correctly mapped to build outputs

Fixes asset loading issues when serving docs from /hub/ subpath

* feat(docs): migrate from AWS Amplify to GitHub Pages deployment

- Remove amplify.yml and Amplify-specific configuration
- Remove _redirects file (not needed for GitHub Pages)
- Add GitHub Actions workflow for automated deployment
- Deploy docs to GitHub Pages on push to main
- Configure CNAME for formbricks.com

The workflow automatically builds and deploys documentation to
gh-pages branch on every commit to main.

* chore(docs): update Node.js version to 22 LTS in workflow

* chore(docs): update pnpm version to 10 in workflow

* fix(docs): remove CNAME from GitHub Pages deployment

CNAME conflicts with DNS records for main marketing site.
Using Next.js rewrites instead, so docs will be accessible via
formbricks.com/hub/ without requiring DNS changes.

* feat(docs): configure hub.formbricks.com subdomain deployment

- Add CNAME for hub.formbricks.com in GitHub Pages deployment
- Update Docusaurus URL to https://hub.formbricks.com
- Change baseUrl from /hub/ to / for root-level hosting
- This provides a cleaner subdomain approach for marketing purposes

DNS Setup Required:
  Add CNAME record: hub.formbricks.com -> formbricks.github.io
