Allow updating the ETH address in MyMeta

What would you like to be added?

Currently the ethereum address associated with a MyMeta account is set when the account is initially created. Additional ETH addresses can be added through the Dicord bot to SourceCred, but they don't affect what is displayed in MyMeta.

There should be a mechanism for updating the MyMeta ETH address.

Why is this needed?

People change their ETH addresses for various reasons…
