fix(web): pin engines.node to 22.x so SWA/Oryx does not grab Node 24

The prior ">=22" made Oryx build with the highest available Node (24.13),
which the Static Web Apps runtime rejects: "Node version 24.13.0 is not
supported. Please use one of the following versions 18, 20, 22." Pin to
22.x so Oryx selects the SWA-supported major. CI setup-node '22' already
resolves to latest 22.x, so build and deploy now agree.
