Use .npmrc to pick up node version (#1697)

All repositories are already using a .npmrc file, so this reduces the
amount of locations to update on node upgrade. Also, this bumps the
release worflow from node 22 to 24, upgrading the default NPM version,
which makes the manual NPM install unnecessary and works around the
issue reported in nodejs/node#62425 (see
https://github.com/inrupt/typescript-sdk-tools/actions/runs/24857693744/job/72774850607)
