schema_spec: Remove unnecessary capture

Thanks to Robert for suggesting `(?:...)`. I didn't know that syntax,
happy I learned something new. Here, I had used parentheses for the "or"
(`|`), but didn't need the captured value. To do the "or" without
capturing, you can use the `?:` inside the start of the parentheses.
