Use sdkReleaseType for tagIsStable in TypeSpec projects

[msyyc]

Changes

For TypeSpec projects, determine tagIsStable from sdkReleaseType pipeline input instead of using judge_tag_preview. Swagger projects continue to use judge_tag_preview as before.

What changed

• Extract sdkReleaseType from pipeline input data
• Add is_tsp flag to distinguish TypeSpec from Swagger codegen
• TypeSpec: tagIsStable = (sdkReleaseType == "stable")
• Swagger: tagIsStable = not judge_tag_preview(...)
• Add test_sdk_generator.py with 9 test cases covering the new logic

Files changed

• eng/tools/azure-sdk-tools/packaging_tools/sdk_generator.py — Updated tagIsStable logic
• eng/tools/azure-sdk-tools/tests/test_sdk_generator.py — New test file

@copilot fix the following ci error:

Run black --check --config eng/black-pyproject.toml eng/tools/azure-sdk-tools --exclude 'templates'
would reformat /home/runner/work/azure-sdk-for-python/azure-sdk-for-python/eng/tools/azure-sdk-tools/tests/test_sdk_generator.py

Oh no! 💥 💔 💥
1 file would be reformatted, 207 files would be left unchanged.

Pull request overview

Updates the packaging tooling to compute tagIsStable differently for TypeSpec vs Swagger code generation runs, using the pipeline-provided sdkReleaseType for TypeSpec projects while preserving existing Swagger behavior.

Changes:

• Read sdkReleaseType from the generator pipeline input and use it to set tagIsStable for TypeSpec projects.
• Keep Swagger projects’ tagIsStable behavior based on judge_tag_preview(...).
• Add unit tests covering TypeSpec vs Swagger tagIsStable behavior plus a few helper-function tests.
