Community Reviewer Fee Input

[acshields]

When Community Reviewer is selected, a field should populate where a user can input the Community Reviewers Fee. This field should be displayed beneath the Copilot Fee field.

If Internal Reviewer is selected, this field should not be displayed.

@acshields we need to move it to August as it needs discussion if challenge api supports the community reviewer fee in prizeSet.
