enhance onboarding user flow

[MohabMohie]

• New users want to be onboarded properly. We lose a lot of potential users because our onboarding docs are too technical and not user friendly enough.
• Instead of linking to GitHub, we should figure out a way to show a parsed version of the github readme inside the user guide itself, this will ensure cross updates and will allow the users to remain on one main website.
• New users want to have clear steps to setup a new project along with all the needed p1 properties:
  • Web
  • Mobile
  • API
• New users want to have clear steps to setup a new Web project using the three different runners we support:
  • TestNG
  • JUnit5
  • Cucumber
• Following the less is more approach we want the user to get a sense of progression when they are getting started.
  • We can split the getting started guide from one single scrollable page to multiple wizard-like small pages.
  • we can leverage Next / Previous / Footer links (breadcrumbs) to ensure easy flow.
  • we can make sure that the user gets all the needed information sequentially, in one place, and without many options.
• New users want to have clear guidance on our support channels:
  • We can list them in a separate page
• New users want to have clear guidance on the types on integrations we support:
  • Jira
  • Xray
  • BrowserStack
  • LambdaTest
  • OpenCV
  • ShutterBug
  • Healenium
  • Slack (was requested)
  • Microsoft Teams (was requested)
