feat: add ability to switch networks

[sirpy]

see also #181

If user is not connected to Celo currently UI just shows unsupported network.
Usually it should be a button or modal triggering switch network request to metamask.
Also since we are just on celo perhaps it should already say switch to celo

Implementation Description:
When user is connected to a non supported network the UI should automatically ask user to switch network

• only trigger switch if user has connected a wallet
• show a modal to user asking to switch network
• trigger switch network on metamask like wallets

Technical description

• handle edge case when connecting to a wallet via walletconnect, and the wallet doesnt support Celo
