chore: run tests with node 16,18 and 20

[tkurki]

In preparation for phasing out 16 and eventual adoption of 20 let's run tests with all these versions for now.

Started to test with Node20 LTS in Docker and noticed build time issues with following SK library, which was not compatible with 20.

-    "eslint-plugin-jsdoc": "^39.3.6",
+    "eslint-plugin-jsdoc": "^46.4.4",

Otherwise seems to run OK and didn't updated node_modules from Node18 LTS. Seems to be very transparent update.

”Issues” ?

npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: '[email protected]',
npm WARN EBADENGINE   required: { node: '^14 || ^16 || ^17 || ^18 || ^19' },
npm WARN EBADENGINE   current: { node: 'v20.4.0', npm: '9.8.1' }

So far only signalk-ruuvitag-plugin required a new compilation due to changed engine.

Removed the jsdoc plugin in 9611319, as I think we don't need it.

@panaaj any ideas about the test that seems to be actually failing with node 20? Works on my machine, fails in github.

I have also tried it locally, also without error.
The error indicates that HTML was returned and not JSON. Trolling the code... all errors are 4xx status within a JSON message.
Pity it doesn't show the full message recieved... this may contain some clues.

Note The Freeboard-SK repo is also experiencing a similar issue, no errors locally but issues with NPM library in github after previously working OK.

Rebased on master, all green now!
