RPC

• The listdescriptors, decodepsbt and similar RPC methods now show h rather than apostrophe (') to indicate hardened derivation. This does not apply when using the private parameter, which matches the marker used when descriptor was generated or imported. Newly created wallets use h. This change makes it easier to handle descriptor strings manually. E.g. the importdescriptors RPC call is easiest to use h as the marker: '["desc": ".../0h/..."]'. With this change listdescriptors will use h, so you can copy-paste the result, without having to add escape characters or switch ' to 'h' manually. Note that this changes the descriptor checksum. For legacy wallets the hdkeypath field in getaddressinfo is unchanged, nor is the serialization format of wallet dumps. (#26076)
