Fix signtool.exe path location for GitHub Actions

At time of writing, signtool.exe is not in the `bin\x64` path that it was
previously in. Instead, it is in the following paths:
* `C:\Program Files (x86)\Windows Kits\10\App Certification Kit`
* `C:\Program Files (x86)\Windows Kits\10\bin\$VERSION\$ARCH`, with the
  following version matrix:
 * `VERSION`:
  * `10.0.17763.0`
  * `10.0.19041.0`
  * `10.0.20348.0`
  * `10.0.22000.0`
  * `10.0.22621.0`
 * `ARCH`:
  * `arm`
  * `arm64`
  * `x32`
  * `x64`

This uses `App Certification Kit`, as that will presumably be the most stable
path for `signtool.exe`.
