Issues for the fontist.org/formulas site

[ronaldtse]

Remaining tasks from @jcbhmr #174

• add a tiny bit more content so its more than just a search box lol
• transfer some of the content from the readme to the docs website
• add the logo to the config
• add a fontist.org root link to the navbar
• any additional configs and such
• adds a github action to deploy the v3 branch to gh pages
• add more pages to the /guide/ folder? split the page into multiple pages? idk maybe just move the "/guide/create-formula.md" out of the /guide/ folder if no other pages lol
• configure the edit link https://vitepress.dev/reference/default-theme-edit-link

I also wonder if the "home page" top left link should directly point to fontist.org instead of the Formulas site.
