Moved some results from ring to semiring.


In Mathlib.RingTheory.Ideal.Operations I moved two results from ring to semiring with the same proof, and two I changed the proof.

There was indeed a mistake in the CI: #8471. Merged master, which should fix it.

Can you please address my other comments as well?

Changed docs of map_of_equiv and comap_of_equiv as requested.

Can you please address my other comments as well?

I hope I did all requested changes. The name map_comap_of_equiv (and all the others) are not mine, so I didn't changed, not to affect other parts of mathlib.
