General fixes - section hide inconsistencies

[wandersoncferreira]

Fixes performed:

• Conversation section without any default value
• Refactor function to include binary files to its own defun
• Break the commit msg to include a single line in the PR page and show the whole body once the commit is toggled
• Improve docs for Doom Emacs users on workspaces and emojify
• Create a proper magit-section-root to the root node in the review buffer
• Fix inconsistencies with magit-section-toggle on Files changed section
  • The solution here is not good yet, I've managed to find some issues with the region used by magit-section but couldn't find why this happens as all of this code is delegated to magit-diff-wash-diff function. Anyway, I added an extra space between each file name and I was not able to reproduce the error anymore. Aesthetically not pleasant, but I'm more concerned with keeping the functionality predictable and stable now.
• Fix comments mis-positioning once send to remote
  • I'll need more time to investigate this one. I was able to reproduce the issue following the descriptions Github review comments are on wrong line #216
• Fix CI
• Check if would be possible to improve Emacs Evil experience in the buffer
