Add a files-only mode

[VP-]

Currently, the file picker supports variations where only folders or both files and folders can be selected. What is missing is a mode where only files can be selected.

Would this be limited to any file? I am thinking if it would make sense to introduce an array of enabled mime types but that would probably be too overengineered?

My use case is just any files, but as long as the list of MIME types would allow wildcards, then that would work, too.

How would an array be passed to the web component?

How would an array be passed to the web component?

It could be a string * or png,jpeg, which we would then just split into an array inside of the component.

Works for me.

PS: Those are file extensions, not MIME types. That's mostly important for the documentation later, otherwise people will try using image/png or video/*.
