Link Delegator adresses to block explorer

[work-0xj4an]

Allow people to click on the delegators addresses that have delegated to a delegate and open the CeloScan of this Address

Problem

If somebody wants to check the Delegators Addresses that have delegated tokens to a Delegate they Can't, celo mondo only shows the firs 6 characters and the last 4 characters of the address.

Solution

Ideally we can make those addresses links to the Celoscan in the way https://celoscan.io/address/XXXXXXXXXX, also will be good to the the same for the Delegate Address.

Alternatives

At least allow people to copy and paste those addresses the same way they can copy and paste the address of the Delegate.
