Date repeat is deprecated

As far as I can tell, Date repeat doesn't appear to be deprecated, or at least, I could't find that reference. I checked several versions of the README: https://github.com/backdrop-contrib/date_repeat. Could you drop in a link to where you saw that documented?

Repeating Dates is currently listed as a similar module, but not a replacement. I don't think we should direct people to use a similar module without a supported upgrade path as part of the upgrade, unless Date repeat is definitely deprecated.

@jenlampton It was un-deprecated by @herbdool:
