[Development] Nominating Liang Qi for HarmonyOS platform maintainer

[Volker Hilsheimer]

Hi,

With the HarmonyOS work merged [1] we have a new platform to maintain, and Liang as the technical lead for the work that got us here is the obvious choice for the role of Platform Maintainer.

So, I hereby nominate him for that role.
