Restore path on Windows is wrong

[auanasgheps]

Describe the bug
Restore path on Windows is wrong, it kinda duplicates it.

Example:

I need to restore C:\Users\John\Desktop\Photos

I select the folder, then I choose the such path.
The restore happens is such folder, but in the folder "Photos" it has re-created all the structure from the root. There's a C folder, then a Users folder and so on.

To Reproduce
Steps to reproduce the behavior:

1. Pick a folder to be restored
2. Enter the correct path of the folder
3. Observe that inside the destination folder the path is createt from the root.

Expected behavior
Restore the files as they are

Platform Info

• Windows 10 22H2 x64
• Backrest Version; 1.6.1

This does need fixing -- a targeted patch related to this was done for Linux, I need to implement and test something similar for Windows.

Relevant lines of code are

backrest/internal/orchestrator/repo/repo.go

Lines 309 to 320 in b7abbf9

	if runtime.GOOS == "windows" {
	opts = append(opts, restic.WithFlags("--include", snapshotPath))
	} else {
	dir := path.Dir(snapshotPath)
	base := path.Base(snapshotPath)
	if dir != "" {
	snapshotId = snapshotId + ":" + dir
	}
	if base != "" {
	opts = append(opts, restic.WithFlags("--include", base))
	}
	}

, which as you can see involve a bit of command crafting. Some work is needed to figure out whether the same or something similar works well on windows.
