Prototype for Unicode.org site

Source repo: unicode-site (source files of pages: src/pages)

Example pages for variable levels of migration:

/policies/ vs current
- Original HTML file as it is.
- The starting point for migrated pages.
/policies/licensing_policy.html vs current
- Dynamically templated, in HTML (enhanced with Astro’s template syntax).
- Actively maintained pages should be converted to this.
/policies/confidential_data_policy.html vs current
- Dynamically templated, in Markdown.
- The choice between HTML and Markdown should be up to the page’s owner.
