Add the option to download previous versions of MCPE from pre-bedrock era

We would like to play legally previous versions of MCPE from pre-bedrock era, or even previous versions of bedrock just like we can do on java. This option would be really good for gaming preservation, and it's understandable that older versions are no longer compatible with modern Android (maybe it could be possible to make them compatible), but at least adding the versions that are compatible with the modern software could be already. Please Mojang! Hear us and preserve these older versions of Minecraft!! 🙏🏼
