Consider disabling RCS1089 (preference for ++ over +=)

[idg10]

Roslynator's RCS1089 warning: Use ++ operator instead of assignment. crops up a lot. It doesn't like this:

count += 1;

and tells you to change it to this:

count++;

I don't like the suggestion in these examples because these statements are purely about the side-effect, so I prefer the presence of an = symbol to emphasize that. My view is that the ++ operators might be a better idiomatic fit in cases where you are also using the value (although compound assignment returns the value in addition to having a side effect, so you can use that in those cases too) but I don't really see any benefit in using ++ in the case shown above, and I see a downside.

I've disabled this warning in a few projects using `Endjin.RecommendedPractices, so I would like to make this part of our defaults.
