Our CI already run test files in parallel, having `node:test` spawns child processes concurrently could lead to oversubscribing the CI machine. This commit sets the `concurrency` depending on the presence of `TEST_PARALLEL` in the env, so running the test file individually still spawns child processes concurrently, and running the whole test suite does not oversubscribe the machine.
