HackStudio: Use String instead of LexicalPath

LexicalPath is a 'heavier' object than a String that is mainly used for
path parsing and validation, we don't actually need any of that in
GitRepo and its related files, so let's move to String :^)

I've also done some east-const conversion in the files that I was
editing for the string change.
