[SPARK-3890][Docs]remove redundant spark.executor.memory in doc

[WangTaoTheTonic]

Introduced in pwendell@f7e79bc, I'm not sure why we need two spark.executor.memory here.

Can one of the admins verify this patch?

It could be because it belongs to both categories (run time environment and application behavior), but yes I think we should remove one.

Actually I don't understant what Runtime Environment category means.

Don't add periods in these two places since it makes it look like part of the code.

[WangTaoTheTonic]

@srowen I checked and found the line contains more than 100 charactors already, so keep the wrapping. The period is also deleted.

Ok, I'll merge this into master and 1.1. Thanks.

[andrewor14]

There shouldn't be a period here, but I'll fix this when I merge it.
