Major BIP 360 Update

In the discussion regarding the nomenclature for a new address class, a suggestion has been made to adopt "pay to script tree hash" or p2sth as the preferred term. This proposed term is considered more accurate and less misleading than other alternatives. The significance of this naming lies in its description of the address class's functionality: the scriptPubKey contains the Merkle root of a tree of scripts. This clear, descriptive naming convention aids in understanding the underlying mechanism of the address class. Furthermore, there's an interesting note on pronunciation; despite the formal abbreviation, there's a light-hearted allowance for it to be colloquially pronounced as "pay-to-something," indicating a casual acceptance of variability in verbal references to the technology.
