Highlights ending with ... has a missing folder/file error

[mlalcevski]

Describe the bug
One of the highlights is labeled "Something ...", the "..." does not work as a folder name in windows so it gets an error every time.

To Reproduce
Download any highlights ending in ...

Expected behavior
Well rename the folder and ignore the ..

Error messages and tracebacks
[Errno 2] No such file or directory

Instaloader version
4.4.4

Additional context

Thanks for reporting. Indeed, creating a folder containing ".." or "..." in the name does not always work on Windows.

Expected behavior
Well rename the folder and ignore the ..

Maybe the dots in "..." should be replaced by another character that is not invalid in filenames and does not collide with characters that might occur in highlight titles, such as "-". There is also #576 with an idea of how we could approach this.

It just does not always work, it never works with dots at the end of a folder name in Windows.
I know nothing about whats talked about in that other issue, but is it a complicated thing to make Instaloader ignore dots or use _ instead in the ending of folder names? Cause this seems like kind of a basic thing to handle for a program that runs in Windows.

If this can't be fixed by replacing the dots would it be possible to make instaloader at least continue and not just quit with this error?
