Add Beta in the Name and Description of Element X

### Your use case

#### What would you like to do?
On Android only in the Aurora Store you see that Element X is a Beta:

Google Play website and app don't show it's in a beta. (Same on iOS/MacOS)
Pls Add a Beta to the Name at the End.
And I would wish that you add in the Description as first sentence something like:
This is a a Beta Version of the next Generation of Element. It's meant for those who like to experiment and help making Element better!

### Have you considered any alternatives?

The issue does not name a repository file, so first locate where Element X's Google Play and iOS/macOS store name and description are maintained. Check the current listings and the repository's project artefacts for the relevant metadata. Done means the name identifies the app as beta and the description begins with the requested beta warning.
