MRIScannerUsage: `device` property missing from compiled schema for v5.0

[apdavison]

Problem

The compiled MRIScannerUsage.schema.omi.json for v5.0 (and the
previously-published latest) is missing the device property from its
properties block. The property does appear in required, creating an
inconsistency: the schema declares device as required but does not define it.

This means tools consuming the compiled schema cannot discover the link
MRIScannerUsage → MRIScanner, even though the analogous
MRICoilUsage → MRICoil link works correctly.

Root cause

versions.json (pipeline branch) pinned the neuroimaging module for v5.0
at commit fe3b615, dated 2026-03-11. At that commit,
MRIScannerUsage.schema.tpl.json did not yet include the device property.
The property was added later in openMetadataInitiative/openMINDS_neuroimaging#60
("Add device field for MRI Scanner in schema", 2026-04-13, neuroimaging v1
branch), but the pin was never updated.

Fix

Update the neuroimaging commit for v5.0 in versions.json from
fe3b615b718065860c342cb2490f1ec5203791c7 to
3f2838a857b0d8832fe2d4617847d92dbf7360bb (current v1 HEAD, which includes
the fix).
