Return error code when any tsc typecheck fails (#5459)

* Return error code when any tsc typecheck fails

* Try with bash

`sh ./scripts/test-types.s` resulted in errors missing `[[`,
which is a bash builtin. It's possible the ubuntu runner is using
some other shell.

* Fix spec type errors

* Switch to node for Windows compatibility
