[Suggestion] Add an option to decrease the number of red squares in the testclient message

Is your feature request related to a problem? Please describe. 99% of my server (including me) uses a shorter chat than default(I made a poll and most use around 200px). The issue is that I am using the Wraith client detection as a way of checking players manually by moderators, and so it happens fairly often. Unfortunately, when using a shorter chat width, the red squares that get sent with it stack up into multiple rows. That makes the feature hard to use/read especially for newer players which is just frustrating and not a good experience. You have to scroll and fight in order to actually be able to read the message that tells you to click.

Describe the solution you'd like I would like to be able to set the number of red squares that get sent. By default, 30 red squares get sent in every line. If you could add a config option for the server owner to be able to reduce this number to, e.g. 20 or every number that they think fits the server best, it would be wonderful.

Describe alternatives you've considered Even better would be to be able to just configure the whole message as a block and not only the parts that contain words.
