This reverts commit 6898fbde33.
PR #2144 added the `license` field but no consumer has been added since
the (like Issue #1768). Since this is not ready yet, I am pulling it
from the 3.0 release.
So far, our main route for pulling a feature from the release has
been to put it behind a `unstable-*` feature flag and to create a
stablization tracking issue. I chose to instead remove the feature
because a write-only field with no effect does not provide values for
people to use in as an early access and so doesn't outweight the cost of
the extra documentation noise and code noise it creates. Additionally,
keeping an `unstable-` feature around when it has such an unknown path
(and time table) to stalbization feels like it violates YAGNI. I'm
uncertain how much of this feature we can implement and not create a
legal trap for users because the crate's license is insufficient for the
final artifact's license. I feel our stabliazation process sshould be
about iteration and collecting user feedback which this doesn't line up
with.
When someone is ready to tackle #1768, it will be easy to revert this
commit and pick up the work again.

> incidentally, how do we feel about adding a rustfmt check to the CI(s)?
yes we should be doing that. you can send another pr that adds the check to the Ci
Comments in 04_using_matches.rs list the config arg
as an optional arg. However, -c --config is currently
a flag arg. This commit sets takes_value to true on
the config arg to make it an "option" argument.
