Removal of bicep-types submodule with migration to pnpm

[brooke-hamilton]

Description

This PR removes the bicep-types git submodule and migrates JavaScript/TypeScript package management from npm to pnpm. The bicep-types dependency is now fetched as a git dependency and built via a postinstall script, simplifying the developer experience.

Key changes:

• Remove the bicep-types git submodule and .gitmodules file
• Migrate from npm (package-lock.json) to pnpm (pnpm-lock.yaml) for:
  • typespec/
  • hack/bicep-types-radius/src/generator/
  • hack/bicep-types-radius/src/autorest.bicep/
• Update GitHub workflows to use pnpm instead of npm
• Update devcontainer configuration for pnpm
• Update Makefiles and build scripts
• Add migration guide for developers with existing clones
