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.

-issues: |
-  Example report — replace with a real one. Onboard WiFi drops the
-  connection under sustained heavy P2P traffic (Bitcoin IBD); a workaround
-  is to run over Ethernet instead. Everything else (Lightning, apps,
-  dashboard) works fine.
-notes: |
-  NVMe via the official PCIe HAT. Boots noticeably faster than SD-card
-  installs.
