Explain to readers how to check what is their device's processor
While working on https://gitlab.e.foundation/e/backlog/-/issues/8120 it was pointed out that some people may not know what the processor of their device is. So in the documentation written via https://gitlab.e.foundation/e/documentation/user/-/merge_requests/1182 we need to add a tip on how to do so.
See this discussion: https://gitlab.e.foundation/e/documentation/user/-/merge_requests/1182#note_590692
