Rollup merge of #77194 - pickfire:patch-7, r=withoutboats
Add doc alias for iterator fold fold is known in python and javascript as reduce, not sure about inject but it was written in doc there. This was my first confusion when coming into rust, I somehow cannot find where is reduce, sometimes I still forget that it is known as `fold`.
