fix(test): stop hardcoding the declared @loopover/engine dependency range

buildEngineVersionDisplay's regression test hardcoded its expected
fallback as the literal string "^3.0.0" -- read live from
packages/loopover-miner/package.json instead, so a real release bump
(confirmed live: the linked-versions release group, #7123, bumped it to
^3.2.1 and broke this) can never silently make the test assert the wrong
value again.
