[CI] Test the suite against Node.js 22, 24 and 26

Add a node-version matrix (22, 24, 26) to the test job so the JS suite runs on
every supported major across the three OSes, replacing the single .nvmrc-pinned
run. Declare the same support in both package.json "engines" fields, switching to
the enumerated LTS-major form Webpack Encore uses (^22.18.0 || ^24.11.0 || >=26.0)
so the odd, non-LTS majors are excluded.
