[Bug]: Read Directory node: glob and exclude don't work on windows

### What happened?

In the Read Directory node, filter glob and excludes don't seem to work properly on Windows?

For example, if I enter `**/*.php` into filter glob, and `**/vendor/**/*` into excludes, the result includes everything from the `vendor` folder just the same.

I also tried using filter globs without excludes, instead using filter globs such as `**/app/**/*.php` - the produces no results.

I suspect maybe the backslashes in Windows paths is throwing off whatever implements glob support?

### What was the expected functionality?

Filter and exclude globs should work.

### Describe your environment

Start with the Read Directory node and locate the implementation of its filter glob and exclude handling. Reproduce the examples on Windows 11, then inspect how Windows path separators are passed to glob matching; done means the PHP filter and vendor exclusion produce the expected results.
