Hey I noticed that we're adding support for versions >=22 here.

In core (MetaMask/core#3611) and metamask-module-template (MetaMask/metamask-module-template#221), we only dropped v16 and didn't add support for v22.

Have we looked into whether there are any breaking changes in v22 we should prepare for? It looks like v21-22 support was previously included in the engines.node package.json field, but not in the github actions.

>=22 is not added but already included in existing/previous >=20.

I would expect that to be caught by tests..?

It looks like v21-22 support was previously included in the engines.node package.json field, but not in the github actions.

So, yes, we're not changing support contract (engines.node) wrt node v22 in this PR, but add test coverage for it here.

Makes sense to expand test coverage and drop support for v21. Thanks for the explanation @legobeat!
