Re: [PATCH v2 5/6] docs/about/deprecated: Deprecate 32-bit arm hosts

For running QEMU in system emulation mode, the user needs a rather strong host system, i.e. not only an embedded low-frequency controller. All recent beefy arm host machines should support 64-bit now, it's unlikely that anybody is still seriously using QEMU on a 32-bit arm CPU, so we deprecate the 32-bit arm hosts here to finally save use some time and precious CI minutes.
