[arku]

Description

The transaction link in the waiting state isn't obvious as there's no visual cue that it's a link. This PR improves the UX by adding an underline style to the link.

@arun1595 could we throw in some padding to give it some breathing space ?

Should be good for merge post that

Hey @arun1595 why does that first line need an underline?

[arku]

@PixelantDesign To provide a visual cue to the user that it's a link and not just plain text.

I think we are mixing informational text with an action. If we should show a link to the etherscan in progress, let's break it out and put it above the GitHub url.
