Discord bot: for each claim message, add a link to our quick vote mark

[loredanacirstea]

The link is:

https://mark.provable.dev/?ipfs=QmdzB48faGpTVZLjPAZA6jLjhZGbdSmX9vN3vcaf5n7MBy&issue=<GitHub issue number>&option=<option number>

E.g.

Vote Url: <https://mark.provable.dev/?ipfs=QmdzB48faGpTVZLjPAZA6jLjhZGbdSmX9vN3vcaf5n7MBy&issue=153&option=3>

Include the link above in the message that announces a claim (or voting option), at the end of the message.
Wrap the link in <>, to force Discord to not render thumbnails.
