Rollup merge of #122209 - onur-ozkan:fix-tidy-path-resolution, r=compiler-errors

fix incorrect path resolution in tidy

Previously, reading the current path from the environment led to failure when invoking x from outside the source root. This change fixes this issue by passing the already resolved root path into `ui_tests::check`.

Fixes #122202
