Update TypeSpec Java dependencies and prepare 0.45.0 minor release (core @ latest main)

[Copilot]

Refreshes Node.js/TypeSpec dependency baselines and prepares the next minor release for @azure-tools/typespec-java. This now moves the core submodule to the latest main commit in microsoft/typespec, and re-syncs generated test assets to match.

• Core alignment

  • Updated core submodule pointer to b2e7e7a0b34a95cd419bdef971a3ce3a3fbc3a29 (latest microsoft/typespec main at update time).

• Minor release prep

  • Bumped typespec-extension package version to 0.45.0.
  • Bumped typespec-tests package version to 0.1.0.
  • Updated typespec-extension/changelog.md with a new 0.45.0 (2026-05-13) entry.

• Dependency refresh and range alignment

  • Updated dependency versions in:
    • typespec-extension/package.json
    • typespec-tests/package.json
  • Aligned typespec-extension peerDependencies with refreshed devDependencies semver ranges.
  • Kept @azure-tools/openai-typespec at 1.11.0 (matching Azure REST API specs baseline).
  • Updated typespec-tests overrides and local tarball reference to the new emitter package version.

• Generated artifacts synchronized

  • Regenerated typespec-extension/package-lock.json after dependency updates.
  • Synced typespec-tests/src and typespec-tests/tsp from core/packages/http-client-java/generator/http-client-generator-test, updating generated Java models/clients/tests and related properties.
  • After moving core to latest main, ran typespec-tests/SyncTests.ps1 again and included newly generated updates (including additional generated test files and metadata changes).
