Test Render.com build on CI

Is your feature request related to a problem? Please describe.
As the Render build might break whenever we update dependencies and configuration in general

Describe the solution you'd like
Add the following steps to the CI:

• Have a public example repository
• Have an action that force-update this repository with a newly generated project
• Use render CLI to create a new service, deploy the example project as a blueprint
• Wait for the deployment to finish (check if render CLI has this capability)
• Run an e2e test to check if the site is working
• Use render CLI to delete the blueprint and all the resources it created
