Update Sphinx LInks with Correct V2 pubkey encoding to add people form registry

[humansinstitute]

Correct the encoding to V2 pubkeys in the boutnies front end.

• Select user with Pub Key V2 e.g. "Pete"
• Click through on QR code for connection details

1. Clicking open in sphinx will correctly open the user in sphinx app -> works correctly
2. Scan QR with Phone -> works correctly
3. Copy and pasting the pebkey and adding via sphinx -> doesn't work
4. Copy and pasting the pubkey into a chat in sphinx -> generates a connect button -> clicking this doesn't work

This is due to the data in the pub key being displayed for copying being incorrect formated.

- V1 Pubkey (General) ->    <part1>:<part2>:<part3>     // Filter Out [V1 format - will be removed]
- V2 Pubkey (Bounties) ->  <part1>:<part2>_<part3>    // This is how the Pubkey is displayed 
- V2 Pubkey (Sphinx) ->     <part1>_<part2>_<part3>   // Allow [correct V2 format]

We need to ensure that the correct encoding is used in displaying and copying of this pubkey.

let part1 = <part1>
let part2 = <part2>
let part13 = <part3>
pubkey = `${part1}_${part2}_${part3}`
