We are using node 16 now, and node 17 is too early to test.

Also update the generated docs.

Just removed package-lock.json and did npm install.

$ npm --version
8.1.2

Plugin polishing. Type checking, linting and formatting for plugins

Because npm doesn't hang anymore with install.
Additionally it is inconvienient maintaining this when updating
package versions inside the template.

It was not updated in a previous release for example.

Seems prettier was getting stuck somehow on the headlamp-plugins
folder... could not find why with debugging enabled. So instead
we just list the folders it should format instead.

So current npm LTS is happy.

Both peerDependencies and peerDependenciesMeta are unused AFAIK.
The typescript version is old, and es-lint package doesn't exist.

So that current npm installs quicker with it.

When using create --link, the package wasn't linked when using the
new npm.

So plugins can `npm run tsc` and see issues.

This is because various libraries in node_modules can be broken,
and we only really care to see if the plugin code type checks.

So the instructions are a bit better on what to do.

Dockerfile: Fix alpine version typo, and separate front and back building

So that if a src/ change is made it doesn't do an npm install again.

So that if a backend part is changed, then the frontend image is
not rebuilt and vice versa.

Fix plugin reinitialization

Upgrade Nodejs 16 versions, and Alpine linux 3.15.0
