Removed extra spaces after marks

[OnkelTem]

To resolve this: #39

First, if I'm not mistaking the entire block:

 (selectedText && sufFirst === " ") ||
        (!selectedText && sufFirst === " ")
          ? editor.replaceSelection(`${prefix}${selectedText}${suffix}`)
          : selectedText && sufFirst !== " "
          ? editor.replaceSelection(`${prefix}${selectedText}${suffix} `)
          : editor.replaceSelection(`${prefix}${selectedText}${suffix} `);

is equivalent to:

editor.replaceSelection(`${prefix}${selectedText}${suffix}${sufFirst !== " " ? " " : ""}`)

Thus, the idea was to add a whitespece if the selection doesn't have another one aftewards.
And if I select a word in word. I get [word ]. selected.
I don't think it's correct behavior and so I dared to change it.

Firstly, thank you so much for contributing. I apologize for neglecting this plugin, as I've been dealing with family issues for the past few months. Looking at this now, I'm not sure why I added the extra space. I do think this looks great, and much cleaner as well! I'll test later today and hopefully release a version before tomorrow. Thanks again!

Sure, n/p!
