Replace wallet address with other strings like SuiNS domain name in the ConnectButton

[universe6666]

Hi Suiet team,

This is a feature request to add support for SuiNS domain name in the ConnectButton component. Right now it's not customizable and only display wallet address when wallet is connected. We want to be able to show SuiNS domain name if available instead.

This is a good point. I am gonna add it to our feature plan.
