Use MatchOptions::default() to disable case-sensitivity

Fixes #621

I find this change reasonable for Windows environments. The Win32 API goes to great lengths to present a case-insensitive view of the file system, even if the filesystem itself is case-sensitive. Therefore, many users reasonably expect this behavior.

However, in Linux environments, it's customary to always treat file names in a case-sensitive manner. For instance, when I run stat *.png on my zsh terminal at a Linux box, it ignores files with a .PNG extension. So this change would conflict with these expectations.

Most other Unix-like, POSIX-compliant systems should behave similarly to Linux in this regard. However, I’ve read that macOS is an exception, being case-insensitive by default. (I'm not a macOS user, so please correct me if I'm wrong!)

What do you think about modifying this PR to use #[cfg] attributes (or cfg! macros) for different glob case-sensitivity based on the target OS? I think this approach would accommodate the different expectations of users on various platforms pretty neatly.

@AlexTMjugador You’re correct, but glob here is only used on Windows so it doesn’t affect other platforms.

Ah, right, my bad, the function this PR modifies has a #[cfg(windows)] just above it that I completely overlooked. Let's merge this then!
