2. Documentation Updates

Documentation and Website Cleanup

This PR includes several cleanup tasks for documentation and website files:

1. Documentation Updates:

   • Updated project name and links in GitHub files (.asf.yaml, PR template, workflows, README)
   • Fixed broken anchor links in documentation
   • Updated docusaurus configuration

2. Website Changes:

   • Removed i18n/zh support for website pages (while retaining Chinese translations for documentation)
   • Renamed and cleaned unnecessary pages (Bootcamp, Community, Contribute, Support)
   • Removed redundant files (coc.md, security.md) in favor of ASF policy documents

These changes streamline our documentation and website maintenance while ensuring all links and references are up to date.

Note: The Chinese translations for documentation pages are preserved, but website pages will be English-only due to maintenance resource constraints.

1. The Footer Security link generates a 404 because you removed the security.md.
2. The is also another Security link 404 on how-to-contribute page.
3. The output from npm run build is generating more warnings than it did in the past.
4. Shouldn't docusaurus catch the 404 errors?
5. I used linkcheck to validate the site running locally. For your reference, attached you will find its output:
   linkcheck.txt

The output from npm run build is generating more warnings than it did in the past.

Yes, most of the issues occurred in the docs/ directory. I would like to collaborate with our documentation contributors to address them in a new PR for these warnings.

Now running the linkcheck and returns:

▶ ~/Downloads/linkcheck/linkcheck --skip-file skip-urls.txt http://localhost:3000 --no-check-anchors
Perfect. Checked 63880 links, 382 destination URLs (1152 ignored). 

For the missing anchor warnings, have created one issue #188. Some of the anchors are right, but cannot be directed to the right place.

You have typos in your commit messages.

They should be fixed.
