doc: Clarify supported Visual Studio versions for windows

The current documentation uses ">=" which implies that any future
version of Visual Studio will work. However, VS 2026 has been
shown to cause build failures on certain branches. This change
explicitly lists 2022 and 2026 as the supported versions to
prevent user confusion.

Fixes: #61449
