[DRAFT] Update the hardware support for HP ProBook 440 G7 in oem-stella.cmit-rhyhorn-meta

[DRAFT][Impact]

 * It should have no impact at all because these changes shall have been applied and verified in the corresponding OEM archive before this SRU process.

[Test Plan]

* Install Ubuntu 20.04.x LTS on HP ProBook 440 G7 and remove oem-stella.cmit-rhyhorn-meta manually if any.

 * Enable focal-proposed and execute the update-manager.

 * The update-manager should show "Hardware support for HP ProBook 440 G7". If not, please change "When there are security updates" and "When there are other updates" in the Updates of software-properties-gtk to "Display immediately", install the older firefox by `sudo apt install firefox=75.0+build3-0ubuntu1` and reboot the system to wait for the update-manager pop up automatically.

 * After it installed oem-stella.cmit-rhyhorn-meta by update-manager and reboot the system, you should see the system booting from the linux-generic-hwe-20.04 kernel.

[Where problems could occur]

 * oem-stella.cmit-rhyhorn-meta is installed but it is not updated to the version in the corresponding OEM archive.

 * The update-manager didn't show "Hardware support for HP ProBook 440 G7" at all.

[Other Info]

 * You can see all oem-stella.cmit-rhyhorn-meta versions on https://people.ubuntu.com/~fourdollars/oem-meta-packages/.
 * I have used ppa:oem-solutions-engineers/oem-projects-meta to verify it before this SRU process.
