build: update minimum version of nodejs and yarn

[phil-davis]

We can no longer build with nodejs v14. node-release, one of the dependencies, requires at least nodejs v18.

nodejs v22 is the oldest release series that is still supported, so it would be nice to require that as a minimum.
But the GitHub workflow runner seems to have nodejs 18 already installed, so allow that.

yarn v1 still has version 1.22.x that works with all current nodejs releases. So require that as a minimum.

Trying to build with nodejs v14 gives:

error node-releases@2.0.47: The engine "node" is incompatible with this module. Expected version ">=18". Got "14.21.3"
error Found incompatible module.

Note: a similar update will be required in https://github.com/owncloud-ci/core/blob/master/php83/Dockerfile.amd64

That is also explicitly using nodejs 14, and it does not work.

yarn install v1.22.22
[1/5] Validating package.json...
error owncloud-js-dev@0.0.1: The engine "node" is incompatible with this module. Expected version ">= 22.23.0". Got "18.20.8"
error Found incompatible module.

The GitHub workflow runner seems to have "node" 18. I will adjust the requirement in this PR to 18.

Solid, minimal change — verdict: approve the version bump, but add a changelog fragment before merge.

Diff scope / consistency — only build/package.json engines: node >= 14.17.0 → >= 18.20.0, yarn >= 1.0.0 → >= 1.22.0. Verified there's no other place pinning these (no root package.json engines, no .nvmrc); the only CI node pin is js-unit.yml node-version: '18', consistent with the new >= 18.20.0 floor. No spot left at the old version. The node-releases >= 18 rationale is correct.

Changelog — missing. core uses changelog/unreleased/ calens fragments and applies them to build/dependency changes (e.g. PHPdependencies...). The green "Changelog lint" check only validates that existing fragments parse — it does not run per-PR enforcement (it's push-to-master only), so it doesn't substitute for one. Please add changelog/unreleased/41662, e.g.:

Change: Raise minimum Node.js and Yarn versions

The minimum required Node.js is now 18.20.0 and Yarn 1.22.0. node-releases,
a build dependency, requires Node.js >= 18.

CI / mergeable — mergeable: MERGEABLE, no conflicts. mergeStateStatus: BLOCKED because required Acceptance / CLI Smoke checks are still pending; JS Unit, PHP Unit, code style, CodeQL all green. Hold for the pending checks.

IMO this is "just" a change in /build, and we don't usually write changelogs for those.

The versions of nodejs and yaml should just be required at build time. Production systems using published tarballs or docker images should not need to worry about that.
