fix(ci): keep stock runner labels in the test matrix

GitHub derives the check-run name from the matrix values, so switching the
matrix to uipath- labels renamed every required test context and left branch
protection waiting on names that can no longer be reported. Keep the stock
labels and map them to the uipath- pool in runs-on instead.
