feat: Add temp path overload for DisposableFileSystem extensions

[MattKotsenas]

The CreateDisposableFile / CreateDisposableDirectory extensions provide two overloads, one automatically creates a subdirectory under %TEMP%, and the other takes a string.

However, the overload that accepts a disposable factory only has one overload that requires a path. In order to make using the extension with custom disposables easier, also provide an overload that automatically creates a subdirectory under %TEMP%.

Also updated unit tests to cover the functionality.

Hi @MattKotsenas
Ok for the new overloads. As for the tests, are you sure we are covering all the old and new overloads? Seems to me there are no new tests in the PR but just a refactoring of existing tests? Can you please let me know? Thanks

Hi there!

The new 3 parameter overloads call the old 4 parameter overloads, so from a coverage perspective they are covered.

From a pedantic perspective, we could add a test to make sure the path parameter is used (e.g. theoretically a future change could ignore path and always use temp). The old tests didn't assert that either, but I'm happy to add a new test that does.

Let me know what you prefer!
