change(rpc): Match `zcashd`'s block template exactly (#5867) 

* Make Zebra's getblocktemplate like zcashd's

* Update snapshots

* Add missing docs

* Fix typo

* Sort coinbase outputs by serialized script for zcashd

* Sort excluding the length byte, make transaction order always stable

* Update snapshots

* Explain that `zcashd` doesn't seem to have a fixed transaction order
