feat(specification): add steps property to Slider in v0.10 basic catalog (google#1462)

* feat(specification): add steps property to Slider in v0.10 basic catalog

- Add optional `steps` property (integer >= 1) to v0.10 basic catalog Slider component definition.
- Add 3 test cases to `checkable_components.json` checking valid and invalid steps property configurations.
- Fix `run_tests.py` monorepo catalog path resolution and AJV reference mapping.
- Update `pnpm-lock.yaml` for AJV test dependencies.

* Revert unexpected changes

* refactor(spec): make catalog alias $id rewriting robust for all custom catalogs
