Add quote from the OpeAtom Chairman to the Oniro landing page

The OpenAtom Foundation told us they would not provide a quote. They changed their mind in the last minute. This quote should be added to the website.

"“We, OpenAtom Foundation, are glad to know that Eclipse Foundation would make great effort with us to build and develop OpenHarmony, the full-scenario next-generation open source OS. We expect a great success together.” - Tao Yang, Chairman of the Board of Directors at the OpenAtom Foundation.

It is an important quote. Can it be included today?
