Merge bitcoin/bitcoin#31531: rpc: Add signet_challenge field to getblockchaininfo and getmininginfo

Browse source 
ecaa786cc1 rpc: add signet_challenge field to getblockchaininfo and getmininginfo (Ash Manning)

Pull request description:

  Signet challenges are currently only available via `getblocktemplate` RPC.
  `getblockchaininfo` and `getmininginfo` both provide inadequate information to distinguish signets. Since these are the RPCs used to determine the current network, they should also provide the signet challenge for signets.

  Test coverage is included in `test/functional/feature_signet.py`.
