update pipelines for new branching strategy

[lilachdavis]

• Add development branch to PR pipelines trigger
• Add deployment pipelines to the dev environment, triggered by a merge to development
• Modify existing build-and-deploy pipelines:
  • Backend: add releastVersion parameter to dotnet build for staging/prod publish
  • Deploy straight to staging without approval gate
  • Extend timeout of prod deployment validation job to allow for a Fri-Tue QA period
