Create list of resources / sample code

[StephenFluin]

Should we put all of the separately hosted repos / docs in one place, like a reference page?

https://github.com/axelarnetwork/axelar-amplifier/
https://github.com/axelarnetwork/cgp-spec (and examples:)

• https://github.com/axelarnetwork/axelar-cgp-sui
• https://github.com/axelarnetwork/axelar-cgp-solidity
• https://github.com/axelarnetwork/axelar-cgp-soroban
  https://github.com/axelarnetwork/axelar-examples/tree/main/examples/amplifier
  https://docs.axelar.dev/learn/cosmwasm-governance
  https://github.com/axelarnetwork/axelar-contract-deployments/blob/main/axelar-chains-config/info/devnet-amplifier.json
