Text - on setup, unclear prompt for Key + Issuer

[sbeitzel]

On initial setup of ShipShape, having dragged a key from my Downloads folder into the window, there's a prompt:

To complete setup, please Key ID and Issuer ID fields below:

This prompt is:

• missing a verb
• missing some hint as to where the Key ID might be found (App Store Connect keys list, on the key's record)
• missing a hint as to where the Issuer ID might be found (App Store Connect keys list, above the list of keys)
