Merge first real hardware report, remove Raspberry Pi placeholder

Lenovo ThinkPad X250 report from issue #1 (submitted via the site form).
Reconstructed cpu/archy_version from the issue body by hand — the
submitted YAML had them glued together with no newline between
("...2.60GHz"1.8.10-alpha), which buildYaml() does not reproduce on these
same field values in isolation (tested directly), so this looks like a
Gitea draft-restore or browser-autofill artifact during actual submission
rather than a bug in the form itself. Values used here are unambiguous
either way. Left the ThinkPad T430 example in place; only removing the Pi
one was requested.
