Section for new joiners

[ggwpez]

There is the section "Becoming a Member" here https://polkadot-fellows.github.io/dashboard/#/membership, thanks for that. I think it should be extended with a "Preparations for joining" step:

• Studying the manifesto and subscribing to its vision + ideals.
• Set an on-chain identity on the Polkadot Relay chain (This needs to include your GitHub handle, see here).
• Put your account address into your GitHub Bio (example)
• Prepare a markdown document to outline your contributions and why you would make a valuable addition to the fellowship (example)
• Post this on the Polkassembly Induction request site from your correct Account
• Ping someone from the fellowship
• They will check the evidence, induct you and open a I Dan promote referendum.
• No further action is required from you now.
• Voting will commence and decide on whether you will be included a a I Dan or not.
