[bug] Unnecessary folder for resources on windows

[gimait]

Describe the bug

Resources are not added correctly to the Wix file, producing a faulty bundle on Windows builds.

Reproduction

1. Add a resource file to tauri.conf.json.
2. Create a Windows build.
3. Install the application using the generated .msi file.

Expected behavior

When adding a resource folder in the path ../res, the resources should be installed in a folder called _up_/res.
I would also expect that a file ../res/resource1.txt would appear in the path _up_/res/resource1.txt.
This is for consistency with other builds and the expected behaviour for the dev environment.

In the current state of the bundler, the generated wix file ignores the standard defined in

tauri/core/tauri-utils/src/resources.rs

Line 10 in 87a2c2f

pub fn resource_relpath(path: &Path) -> PathBuf {

It also adds an extra directory for each file with its file name, moving the resources to folders with their own name.

This means that a resource ../res/resource1.txt gets copied to res/resource1.txt/resource1.txt, rather than the correct _up_/res/resource1.txt.
