Link to a Polkadot wallet in the farmer README

[teor2345]

When I was setting up the farmer, it was hard to work out which Polkadot wallet I could use.

The browser extension worked for me, but the website didn't.

I tried: https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Feu-0.gemini-3h.subspace.network%2Fws#/explorer
But I got the message: "Waiting to establish a connection with the remote endpoint."

Code contributor checklist:

• I have read, understood and followed contributing guide

Makes sense to me. For website RPC URL is invalid, simply select "Subspace Gemini 3h" from test networks in the menu that is opened by clicking in top left corner. Wondering how you ended up guessing RPC URL though.

I looked at the open ports in the space-acres log? I think?

Space Acres doesn't connect to any RPC, so it is unlikely. In fact it is technically still having RPC enabled, but we should disable it once it becomes possible (we need to replace spawn_tasks for that, which is now possible with paritytech/polkadot-sdk#3166 and paritytech/polkadot-sdk#4457 that are both upstream and downstream in our fork).
