Merge bitcoin/bitcoin#24370: rpc, cli: describe quality/recency filtering in getnodeaddresses and -addrinfo 
ce690847b69eb80b0232f818152dbb1db7c4c61a cli: describe quality/recency filtering in -addrinfo (Jon Atack)
7c975614c0fc6ff2084a1708a4c1f0368a4bc98f rpc: describe quality/recency filtering in getnodeaddresses (Jon Atack)

Pull request description:

  Addresses #24278.

  ```
  $ bitcoin-cli help getnodeaddresses
  getnodeaddresses ( count "network" )

  Return known addresses, after filtering for quality and recency.
  These can potentially be used to find new peers in the network.
  The total number of addresses known to the node may be higher.
  ```
  ```
  $ bitcoin-cli -help | grep -A3 addrinfo
    -addrinfo
         Get the number of addresses known to the node, per network and total,
         after filtering for quality and recency. The total number of
         addresses known to the node may be higher.
  ```
