✨ [Go] Built-in support for converting fs.FS into Directory

[GreenCappuccino]

What are you trying to do?

fs.FS is a common interface for filesystems in Go. Copying files from an FS currently requires authors to walk through the filesystems and add the files into the Directory. (For example, as in here, and described here) A built-in conversion function can simplify this process.

Why is this important to you?

Since this is a relatively common need, it could be worth putting into the Go SDK.

How are you currently working around this?

Implementing the same walk operation.
