generateblocks is missing in daemon RPC documentation

[dimalinux]

Developers need to test their code and generateblocks is quite handy. I've used it a lot, but still could use the guide entry so I could finally learn what the prev_block and starting_nonce input values are used for.

Where it is missing: https://github.com/monero-project/monero-site/blob/master/resources/developer-guides/daemon-rpc.md

C++ reference: https://github.com/monero-project/monero/blob/v0.18.1.0/src/rpc/core_rpc_server_commands_defs.h#L1076-L1107

Example Use:

Start monerod in test mode:

monerod --detach --regtest --offline --fixed-difficulty=1 --rpc-bind-ip 127.0.0.1 --rpc-bind-port 18081

Request:

curl http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"generateblocks","params":{
"amount_of_blocks":1,
"wallet_address":"42eTJxqsYwsSpFCRUp19vPAXNruqAUqnFMY2XN198643Ukrera958dY4qbRdoaoCVffhbC7ro4nzVBMw1E8ip7LAKG3SrsU"}' -H 'Content-Type: application/json'

Response:

{
  "id": "0",
  "jsonrpc": "2.0",
  "result": {
    "blocks": ["49b712db7760e3728586f8434ee8bc8d7b3d410dac6bb6e98bf5845c83b917e4"],

    "status": "OK",
    "untrusted": false
  }
}
