Add `monospace` formatting in commit messages

[sebastianzander]

I regularly use the backticks (`) to mark certain words in my commit messages like functions, classes, etc. In GitHub this is even translated to a monospace formatting, at least if it is in the first line of the commit message, like e.g.:

If the commit message has more than one line, the others will in general be formatted in monospace on GitHub.

I would love to see GitLens supporting monospace spans where ever a commit message appears, most importantly in the Commit Details and in the tooltip that appears whenever you hover the mouse pointer over a commit.

Best regards Sebastian

P.S. love your extension ❤️
