Add check for Windows-forbidden characters in the filename

#352

[sebastiaanspeck]

Adding a real 111<.md file causes the checkout to fail on Windows (obviously).

We could argue if we want to name the new check TLDR110, since all of those affect the filename, and rename the previous TLDR110 to TLDR111.

@kbdharun the 👍🏼 means that you agree? If so, I will change the new check to TLDR110.

Personally I would say we shouldn't rename TLDR checks as people may be relying on the error codes. 🤔 Especially as this has been out since March. 👀

Even if it looks a bit weird having some that are related to files in different locations, it should be in the order we add them. 👍🏻 Otherwise, if we add a filename rule in 20 rules time, we'd have to reorder them all again.

I will add a line in the changelog and then this PR is GTG
