4.37: highlight that (Legacy) Qemu VMM + osxfs will be removed in a future version

For filesharing, anyone still using osxfs should switch to virtiofs which
is faster and more stable.

For running the Linux VM locally, anyone still using Qemu on Apple Silicon
should switch to virtualization.framework which is also faster and more stable.

In case someone hits a problem and needs help, include links to support and
the github issue tracker.

Some history:

- In 2020 osxfs was marked as legacy (Docker Desktop 2.4.2.0).

- In 2023 with the release of macOS 14, all supported macOS versions (current
release plus previous two) use virtualization.framework by default.

- In 2024 (Docker Desktop 4.36) Qemu as a VMM was marked as legacy in the UI.
