build(Windows): fix redoing version generation (#21880)
Problem: On Windows, neovim's version is generated every time nvim is
built, even if code hasn't been changed.  That is because version
generation is done based on a hash matching of a file and the content of
the file.  And in Windows they don't match, because of the DOS
line-endings.

Solution: Write the file containing nvim version with UNIX line-endings.
