Merge pull request #18545 from bmcdonald3/hash-docs
Update documentation to reflect the new record
hash special method
In #18343 the functionality to override the map hash function by defining a myRecord.hash method was added, but I didn't add any docs in that PR since I was (unreasonably) scared to add docs for the first time. This PR adds that documentation and updates the special methods primer to reflect that change.
