Which issue does this PR close?

N/A

Rationale for this change

We have a bunch of new crates, so let's update the labeler to reflect that

Here is the contents of datafusion:

What changes are included in this PR?

1. Update labeler.yml to label PRs using updated crate names
2. I also added the relevant labels to this repo (see https://github.com/apache/datafusion/issues/labels)

Are these changes tested?

No -- I figure we'll test them "in production" and update the rules as needed

Are there any user-facing changes?
