Pin node to version 22.11

[browniebroke]

Description

Ou CI broke a few days ago, the Docker Gulp job started failign on all branches with ERR_REQUIRE_ASYNC_MODULE.

We specify only the major node version, but the latest v22.12 introduced a change which is impacting us, or at least one of our dependency:

With this feature enabled, Node.js will no longer throw ERR_REQUIRE_ESM if require() is used to load a ES module. It can, however, throw ERR_REQUIRE_ASYNC_MODULE if the ES module being loaded or its dependencies contain top-level await. When the ES module is loaded successfully by require(), the returned object will either be a ES module namespace object similar to what's returned by import(), or what gets exported as "module.exports" in the ES module.

The root cause is from gulp-imagemin which is doing a top-level await:

• Error with node 23.1 sindresorhus/gulp-imagemin#389

Checklist:

• I've made sure that tests are updated accordingly (especially if adding or updating a template option)
• I've updated the documentation or confirm that my change doesn't require any updates

Rationale

Pinning the version to fix our CI until the dependency is fixed or we figure out a better way to fix it.
