Add describe_check function

[mpadge]

Not sure who's maintaining this package these days, but ... All tests have a "description" item which is not exposed to the users at all. This function simply does that, which I think is really useful.

Maybe add a snapshot test for one of the most stable checks?

Writing the comments made me wonder whether there should be some flagging of non-specific-enough expectations for packages that use testthat.

Maybe add a snapshot test for one of the most stable checks?

Done, as snapshot of describe_check(all_checks(), which I think will be useful, in spite of needing updating every time the list of checks changes.
