429 errors with add_contributors()

[sbfnk]

We're running into 429 errors (too many requests) with add_contributors() and tracked this down to the check_github_urls() call. A simple remedy would be to expose the check_urls argument to add_contributors().

This issue is causing epiforecasts/EpiNow2#664

Just implemented a better work-around for a similar 429 error in ropensci-review-tools/dashboard@c70e7af. I'll copy that code over here to fix. Thanks for the heads-up!

Great, thanks!

@sbfnk The check_urls parameter has now been exposed in the main add_contributors function, as you suggested, plus additional error handling implemented for the checking calls themselves. Any errors should now just "fail gracefully", and the call should proceed regardless.

These changes should be on an updated CRAN version soon.
