chore(ci): fix the npm publish job and bump to 1.33.0

[kevbarns]

Fix the npm publish job and release 1.33.0

Two commits, to be merged after #506 so that 1.33.0 carries both.

1. The publish job has been broken since npm 12

publish_on_npm pins node 20, then runs npm install -g npm@latest. npm 12 declares
engines: {"node": "^22.22.2 || ^24.15.0 || >=26.0.0"}, so that install fails with
EBADENGINE and the job dies before ever reaching npm publish:

npm error code EBADENGINE
npm error Required: {"node":"^22.22.2 || ^24.15.0 || >=26.0.0"}
npm error Actual:   {"npm":"10.8.2","node":"v20.20.2"}

That is why 1.32.5 has a git tag and a GitHub release but never reached npm: in
run 30816134336,
create_github_release succeeded and publish_on_npm failed, leaving latest on 1.32.4.
Any version bump would fail the same way until this is fixed.

The job moves to node 22, which is already what the test job uses.

2. Bump to 1.33.0

Minor rather than patch: #505 adds a new opt-in CLI command
(react-dsfr only-include-used-components) and a new bin entry, which is additive
public surface. No breaking change.

The release also carries the two fixes that were tagged 1.32.5 but never published
(#493 Footer categoryName as ReactNode, #501 SideMenu plain button), and, if merged
after #506, its only-include-used-icons fixes.

npm will go 1.32.4 → 1.33.0. The v1.32.5 tag stays as a release that never shipped;
npm does not require contiguous versions.

Merge order

#506 first, then this. Merged the other way round, 1.33.0 would ship without #506 and
that fix would need a 1.33.1.

Pull request overview

This PR updates the release pipeline to restore successful npm publishing (by aligning the publish job’s Node version with the repo’s Node 22 baseline) and bumps the package version for the 1.33.0 release.

Changes:

• Bump @codegouvfr/react-dsfr version from 1.32.5 to 1.33.0.
• Update the publish_on_npm GitHub Actions job to use Node 22 so npm install -g npm@latest no longer fails due to engine constraints.
