Update Celerity map parser for new docblock code

Browse source 
Summary:
After D16431, listing the same `@annotation` multiple times makes the docblock parser return a list.

We have some resources which list `@requires` or `@provides` several times, but don't handle the new parser properly. Make the code more flexible, since this is a reasonable way to specify the annotations.

See also D16432. This produces a failure in this form:

```

Test Plan: Ran `bin/celerity map`, no more warnings and no change to the actual map.
