Add support for Raspberry Pi OS ARM64

[SuperJMN]

It's now officially supported and I can say it's getting traction every single day. Please, support it :)

Thanks!

Yeah, we've switched to VS2022 for our other projects too.

I'm heads down getting a demo ready for next week, but I'll have time to look at this next weekend.

Hi Jefflill and others,
have a beta 64Bit Support for raspbian working since yesterday. I want to test this feature in deep before deploying a new version. Maybe till end of this or next week I'll do the deployment? Have to see...

@jefflill /@ALL Do you know if a Microsoft feed exsists to get all actual supported Core Versions (3.1/5/6)? There a MS pages describing the versions - but I haven't found a feed so far. Consulting such a feed and dealing with it should be much simpler than maintaining the version json every time a new .NET Core modification/service pack gets released. And MS has plenty of this modifications the last time. ;)
Thanks a lot!
Cheers!
