Update .NET docs on Ubuntu now that .NET is available in default distro repos

[omajid]

Certain versions of .NET are now available in the default repositories on certain versions of Ubuntu.

We should probably update the .NET install docs to reflect how to "correctly" install .NET. Otherwise, it's possible users will pick up an incorrect mix of packages, or pick up packages from the Ubuntu feed when they want it from the Microsoft feed (or the other way around).

We suggest using the distro-only packages for CentOS (Stream), Fedora and RHEL already.

Do we also need to update https://docs.microsoft.com/en-us/dotnet/core/install/linux-package-mixup for Ubuntu?

Hi @omajid I'm opening up a PR to handle a bunch of different changes in the install docs. Do you have a link to the ubuntu information so I can make sure I rewrite the content appropriately?

Sorry, I don't. Hopefully @mirespace does.
