.NET Snap Ownership Transfer from Microsoft to Canonical

### Summary
In May 2024, the responsibility for building, publishing, and supporting .NET Snaps will be transferred from Microsoft to Canonical. This transfer will also leverage Canonical expertise with Snap packaging and enhance the design of .NET Snaps for added improvements. Canonical is currently working on creating new .NET Snap packages.

You will continue to leverage Snaps to install/update .NET for all the supported .NET versions (currently include .NET 6, .NET 7, and .NET 8). Like the current state, you can use Snap to install .NET SDK and .NET Runtime.

### Important Dates, Impact, and Call to Action

1. The ownership transfer of the existing .NET Snaps from Microsoft to Canonical.

Date: May 2024 (_Stay tuned for exact date_)
Impact: No impact on .NET Snap user
Call to action: No action needed.

2. Transition from the old Snap packages to the newly built Snaps by Canonical.

Impact:
- New Snap will package Canonical-built .NET. As Canonical does not build/publish .2xx and higher SDK feature bands due to breaking changes, new Snap will only support .1xx SDK feature band for the lifetime of a major .NET version.
- .NET previews (.NET 9 previews) will not be available to install via Snap.

_Stay tuned for date and call to action to switch from old to new .NET Snaps._
