Add renaming smoke test and fix broken README badge (#689)

The README linked a 'renaming' badge to a non-existent rename_test.yaml
workflow, so the badge never rendered. The samples repo had no renaming
check at all.

Add the missing renaming function, mirroring the abap2UI5 framework repo:
- .github/workflows/test_rename.yaml runs it on every pull request
- npm run rename runs abaplint --rename with the checked-in config
- .github/abaplint/rename_test.jsonc renames the z2ui5 namespace to a
  placeholder and syntax-checks the result, scoped to the portable src/01
  set (basic samples plus the abap2UI5 framework dependency)

Point the README badge at the real workflow file (test_rename.yaml),
matching the framework repo's naming.
