chore: update JavaScript FAQ items now that the site is static

[magnus-madsen]

Updates the three JavaScript-related FAQ items to reflect that the site is now static HTML:

• "Why does the website require JavaScript?" → "It no longer does. Well, almost: the carousel spins better with JavaScript, doesn't it?"
• "The page does not load without JavaScript enabled…" → notes the site is now static HTML and browsable with curl
• "This site requires JavaScript" → counter of people who offered to help refactor to static html bumped from 0 to 1, linking to feat: rewrite to Astro #165, plus a new line: "People who can now complain about the CSS: everyone."
