core-updates probably won't be merged for a long time, so a graft might
be needed in the meantime.

Basically, what you need to do is:

  * keep the old ruby@2.7.4 package definition
  * add a ruby@2.7.6 package (as (define-public ruby-2.7-fixed [...]))
  * in ruby@2.7.4, add a field
    (replacement ruby-2.7-fixed) ; security fixes

and verify that some Ruby-using dependents still seem to work.

That way, we can use a fixed ruby@2.7.6 on master.

(This assumes that ruby is graftable -- this assumes that ruby is
ABI-compatible, otherwise the grafted dependents won't work.)

Greetings,
Maxime
