Remove redundant whitespaces on the api key auth popup

[hankovich]

Description

On the API key auth popup 2 spaces are displayed between Bearer and (apiKey). Usually I just copy paste Bearer (apiKey) from the popup to the textbox and the replace (apiKey) with the actual bearer token. Of cource, my requests receive 401 because the server interprets additional space as the token's first character. This PR removes extra whitespaces.
