Whether this is the best ordering is subjective, but I prefer a specific
ordering like this until I see a better one (perhaps by categories or
so).

The inputs expect `true` to enable the copying behavior. It wasn't
really clear from the action.yml nor from the readme that these are
boolean flags. By specifying the default as `false` this becomes clear.

Ultimately, an empty input would still disable the copying behavior, but
that's less relevant than the knowledge that this is a boolean flag.

This change doesn't affect the usage or implementation.

I'd like to keep the descriptions of the inputs aligned where
possible/useful to avoid confusion about what they do.

The current implementation is not aligned with this description. It
copies the currently open review requests and does not request reviews
from those that already reviewed the original pull request. Let's adjust
the name and the description to fit what it does: copy the requested
reviewers not the actual reviewers.

We can log the entire response for any of the failed requests. They may
contain valuable info.
