Update recommended config to allow fieldset to have the radiogroup role

[hallzac2]

Description

Update the recommended config to allow fieldset to have the radiogroup role. Also update the test for this rule to have an entry for this change and one for the presentation role.

MDN lists both radiogroup and presentation as valid options for the role attribute on a fieldset.

This fixes #743.

Testing

1. Pull this branch (or apply these changes as a patch)
2. Run npm i
3. Run npm run test, no tests should fail

I only added this to the recommended config for now. Is this something that should be added to the strict config as well?
