Define Monorepo Configuration & Upgrade & Fix for Templates

[JacobMGEvans]

Develop a specific configuration approach for handling Templates in the workers-sdk repository. Templates created externally and later integrated into workers-sdk do have unique local setups and configurations, necessitating a tailored solution.

• Upgrade Templates
• Fix any broken Templates (should work out of the box)
• Specific Monorepo configuration
  - Try to get all the templates under the same monorepo config
  - Isolate templates
