Bump TypeSpec dependencies to latest stable and next pre-release versions

[Copilot]

Updates TypeSpec-related packages in packages/typespec-ts and packages/typespec-test to align with TypeSpec 1.12.0 stable, and uses the next dist-tag for test/spec companion packages.

Version updates

packages/typespec-ts devDependencies + peerDependencies and packages/typespec-test dependencies:

Package	Before	After
@typespec/http-specs	0.1.0-alpha.37-dev.6	0.1.0-alpha.37-dev.6 (next tag, unchanged)
@azure-tools/azure-http-specs	0.1.0-alpha.41-dev.1	0.1.0-alpha.41-dev.2 (next tag, bumped)
@typespec/spector	0.1.0-dev.4	0.1.0-dev.4 (next tag, unchanged)
@typespec/spec-api	0.1.0-dev.3	0.1.0-dev.3 (next tag, unchanged)
@azure-tools/typespec-client-generator-core	^0.68.2	^0.68.3 (latest stable patch)

The test/spec packages (@typespec/http-specs, @typespec/spector, @typespec/spec-api, @azure-tools/azure-http-specs) track the next npm dist-tag. @azure-tools/azure-http-specs was bumped from 0.1.0-alpha.41-dev.1 to the current next tag 0.1.0-alpha.41-dev.2. pnpm-lock.yaml updated accordingly.

@copilot run npm run integration-test-ci:azure-modular under packages/typespec-ts/ to fix ci error.

Done. @azure-tools/azure-http-specs@0.1.0-alpha.41-dev.2 added a new namespaceModelSerializable operation to the azure/client-generator-core/usage spec (with NamespaceModel/NestedNamespaceModel types). I regenerated the baseline (index.d.ts) and added the missing test case in azureClientGeneratorCoreUsage.spec.ts — commit Regenerate usage baseline and add test for namespaceModelSerializable.

@copilot run npm run integration-test-ci:azure-rlc under packages/typespec-ts/ to fix ci error.

Done. The new azure-http-specs@0.1.0-alpha.41-dev.2 adds a namespaceModelSerializable endpoint to the azure/client-generator-core/usage spec. I regenerated the RLC baseline (index.d.ts) and added the missing test case in azureClientGeneratorCoreUsage.spec.ts — all 788 azure-rlc tests pass (commit Regenerate usage baseline and add test for namespaceModelSerializable (azure-rlc)).
