Website updates and fixes

[bugarela]

Hello

This

1. Fixes a broken link
2. Fixes the number of steps (going from 1 to 3 to 5) on getting started page. I think this fix requires a force reload as css is cached.
3. Adds some cards to point out to other tools to both home page and getting started page
4. Adds a tooltip to try the LLM kit to get started via agents (in getting started). I also changed the CSS to make this level of tooltips purple instead of an weird orange. This only affects one other tooltip in the checking properties page, which looks better in purple too.
5. Adds an icon to the navbar for the twitter page. Nextra doesn't support having two "chat" icons and we are already using it for Telegram, but adding an extra children works fine.
6. Updates our twitter handle in OG metadata
