### Brief description of your issue

ImageMagick seems to be not entirely organized according to the same `\` scheme. Some of the packages can be found directly under `\\` , some under `\\`, some under `\\\`. This leads to inconsistent results when searching, or trying to detect and update packages.

currently tree:
* winget-pkgs/manifests/i/ImageMagick
* ImageMagick
* 7.1.2.10 *(= Q16-HDRI/7.1.2.10)*
* Q16/7.1.2.11
* Q8/7.1.2.11
* Q16-HDRI/7.1.2.8
* Q16/7.1.2.8
* Q8/7.1.2.8

expected:
* winget-pkgs/manifests/i/ImageMagick/ImageMagick
* Q16-HDRI
* versions
* Q16
* versions
* Q8
* versions

### Steps to reproduce
