Giles Odigwe 1249275997 Python: Remove experimental marker from Skills API (#6974)
* Python: Remove experimental marker from Skills API

Promote the Skills feature from experimental to stable, mirroring
.NET PR #6861. Removes the @experimental(SKILLS) decorators from the
skills APIs and the SKILLS ExperimentalFeature enum member, updates
tests and samples accordingly. MCP skills (MCP_SKILLS) remain
experimental, matching the .NET change.

* Add experimental-stage assertions for MCP skills types

Guard MCPSkill, MCPSkillResource, and MCPSkillsSource against accidental
promotion by asserting their docstring warning block and
__feature_stage__/__feature_id__ metadata remain experimental (MCP_SKILLS).

* Remove redundant stable-stage test for Skills API

Drop TestSkillsStableStage: asserting the absence of experimental
markers on a released API is not meaningful, and the feature-stage
decorator machinery is already covered by test_feature_stage.py.
