fix(test-runner-junit-reporter): update XML snapshots for workspace cwd

npm workspaces run test scripts from the package directory, not the
repo root. The test runner computes file paths relative to cwd, so
XML output paths are now relative to the package root (test/fixtures/...)
instead of the repo root (packages/test-runner-junit-reporter/test/...).

Updated expected XML snapshots to match.
