Lock node version to 18.16

[huozhi]

As we're using nodejs with latest version of 18.x on CI, there's a new behavior change of url.fileURLToPath that didn't join the paths as expected

locally with node 16.x or 18.16

/private/var/folders/mh/y8kwzkls6v3_w3_k6q384cw80000gn/T/next-install-b033b516612809c6fb0a0de77c6e50f7d7f8af34dfd3d01812b99345352dc992/node_modules/.pnpm/file+..+next-repo-7e52b07043e986127273a2d951e5c412b0dd45fb24eb34001bd372e2afff79db+packages+n_vyqu6i4c4i3efp5pqsaeaoe5s4/node_modules/next/dist/compiled/@vercel/og/noto-sans-v27-latin-regular.ttf

in the actions runner with node 18.17 it's

/tmp/next-install-8efaa47c1546bed07990d8f130decceb6536e1a36146e7885cb68e3c3dea21f7/node_modules/.pnpm/file+..+next-repo-9679355e05341947e7aa0b42c994e3ac_krcuriy4thl7zawouf7sswlrgy/node_modules/next/dist/compiled/@vercel/og/index.node.js/../noto-sans-v27-latin-regular.ttf

You can see that index.node.js is still present in the path as a folder which is unexpected

index.node.js/../

Out of curiosity: what problem does this solve?
