This commit improves the revert script for store apps to handle
scenarios where `Get-AppxPackage` returns multiple packages. Instead of
relying on a single package result, the script now iterates over all
found packages and attempts installation using the `AppxManifest.xml`
for each. This ensures that even if multiple versions or instances of a
package are found, the script will robustly handle and attempt to install
each one until successful.
Other changes:
- Add better message with suggestion if the revert code fails, as
discussed in #270.
- Improve robustness of finding manifest path by using `Join-Path`
instead of basic string concatenation. This resolves wrong paths being
built due to missing `\` in file path.
- Add check for null or empty `InstallLocation` before accessing
manifest path. It prevents errors when accessing `AppxManifest.xml`,
enhancing script robustness and reliability.
- Improve error handling in manifest file existence check with try-catch
block to catch and log exceptions, ensuring uninterrupted script
execution in edge cases such as when the script lacks access to read
the directory.
- Add verification of package installation before attempting to install
the package for increased robustness.
- Add documentation for revertCode.
