Description

This PR finalizes the clean-up of our OUDS Web main branch before starting the development:

• For pages that are mentioned in the side menu:
  • Remove the content of the Markdown files
  • Use the strike-through approach in the side menu to inform users that the content is not available
  • For each of these pages, a callout is displayed in the page to inform that the content is not yet available
  • Note: some easy pages in the About section are kept as they already work
• For the homepage, I kept only the content that is usable as is
• The version dropdown has been simplified
• The "Design Guidelines" and "Solaris Icons" links have been removed
• The footer has been adapted with the available content
• The examples page is empty and all the examples have been removed
  • I've created a fake example (not mentioned in the examples page) just in order to keep the compilation/packaging system

Please be aware that when some resources were not used anymore, they were dropped from the repository as well.

OUDS Web and Bootstrap versions

Boosted and Bootstrap were using the exact same versions at the same time. Now we have to deal with different versions, and so, some Hugo params must be split:

• New bootstrap_docs_version parameter set to 5.3
• New bootstrap_current_version parameter set to 5.3.3

System of URLs

This PR fixes the URLs issues and configuration and works when:

• npm run start
• https://deploy-preview-2612--boosted.netlify.app/
• npm run docs, then run php -S localhost:8008 in _site directory
• npm run release, mv _site/ouds-web /tmp, git checkout gh-pages, rm -rf ouds-web/*, mv /tmp/ouds-web/* ouds-web/, then run php -S localhost:8008

Instead of adding a /ouds-web everywhere in the code like tried in https://github.com/Orange-OpenSource/Orange-Boosted-Bootstrap/pull/2614/files, a modify-site.sh script does it only when we build the documentation targetting gh-pages.
It allows running the documentation locally and via Netlify as usual, and we'll only need to drop the usage of this script whenever OUDS Web will replace Boosted.

Please note that there are some edge cases that don't work for now until the new DNS is correctly set up, but should be automatically handled in a near future:

• Redirection like https://orange-opensource.github.io/Orange-Boosted-Bootstrap/ouds-web/docs have been configured to use the newly created DNS web.unified-design-system.orange.com that will redirect to https://orange-opensource.github.io/Orange-Boosted-Bootstrap/ouds-web
• CSS used by Storybook in https://github.com/Orange-OpenSource/Orange-Boosted-Bootstrap/pull/2612/files#diff-22bfa436a490448858048de4423952a0f8db74eb9667a997e5af2cf1d2c94a38 won't work until the new DNS is correctly set up

After the merge

•  Take into account [OUDS] Docs: empty pages content #2612 (comment)
• Make modify-docs.sh script work on Windows too
• Generate patch versions (0.0.1, 0.0.2, etc.) with the real process to check that all download references and links work as expected (zip files, examples packages, npm packages, etc.)
• Fix ReferenceError: boosted is not defined, and handle the JS part correctly
• We'll need to track everything that has been temporarily removed in [OUDS] [Tracking] Documentation content #2611 so that it can be reintroduced step by step for OUDS Web

Storybook

The following URLs should work:

• Locally after a npm run start: https://localhost:9001/storybook
• In Netlify: https://deploy-preview-2612--boosted.netlify.app/storybook
• In gh-pages: https://orange-opensource.github.io/orange-Boosted-Bootstrap/ouds-web/storybook
• With the DNS: https://web.unified-design-system.orange.com/storybook
