Basic documentation

[howamith]

Add content to the Documentation page on the frontend application. Topics should include, but not be limited to:

• Hosting/ running
• Design and architecture? i.e what is monitor? What is a job? When is a job late? How often do we check and notify for late jobs?
• API docs (if not already covered in #14
• code snippets/ examples (use tabs here - and build the docs as per how we want the integrations to look!)
  • Python (decorator)
  • Bash (using curl and jq)
  • Rust (reqwest)
  • NodeJs (TypeScript and/ or JavaScript?)
  • cron-mon-cli

For API docs there's https://github.com/koumoul-dev/vue-openapi which might be helpful, but I'm not sure how easily it could be made to fit the rest of the app's aesthetic. https://nuxt.com/modules/nuxt-openapi-docs-module might be better but it uses Nuxt, however it does say it's using reusable Vue components so we could just use those.

May also e worth a look at https://github.com/scalar/scalar
