Revert "docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation"

This reverts commit 1d0a8eba38cdddd028ea02c6e0b68f0a4c9a3cbf.

The commit made the wrong assumption that 64-bit distros are most
common these days on arm devices, but as Liviu Ionescu pointed out,
the recommended OS for the very popular Raspberry Pi boards is still
the 32-bit variant, and thus likely still used by a lot of people:

Thus it's likely still a little bit too early to put this host
environment on the deprecation list and we should wait a little
bit longer 'til 64-bit distros are the predominant ones.
