chore: add staging and prod deployment

[Daniel-Wh]

What's missing

Currently, the only the deploy step that exist is deploying to dev.devopswithme.net. Need to add two more deploy steps. One for staging.devopswithme.net and one for production www.devopswithme.net

Steps to resolve

Probably best to do this after bringing in Terraform so the staging and production environments can be generated through IaC.

• Add IaC for staging environment
• Add IaC for prod environment
• Add deploy step (gh action) from develop to main to kick off staging deployment
• Add deploy step on trigger (gh action) to kick off production deployment
