Add KARMA test suite to enable testing

[stockiNail]

This PR is adding test suite in order to enable the tests.

The source was chartjs-plugin-annotation and maybe something is not "perfect".

What cannot do is to register the plugin globally (try in several ways without any success) therefore in this PR the plugin has been adding in the first test case.

EDIT: the global registration was fixed putting it in beforeAll hook. Thanks @kurkle

I had a look to chartjs-plugin-datalabels which, like this plugin, doesn't have the auto registration. Nevertheless I wasn't able to enable it globally. :(

Oh, how nice! Than you!

Did you try adding a beforeAll handler in test/index.js?

No... only in beforeEach. Let me try

@kurkle I'm going to add some test cases because I'll have a couple of PR and I want to make sure do not destroy anything!

I tweaked the CI to do coverage analysis on sonar cloud too (and removed windows runner, because I don't know how to do coverage on multiple osses and its slow etc)

So, the quality gate is failing currently because test coverage is too low.. looking forward on your new test cases to fix that! :)

[stockiNail]

I'm doing... I have added chartjs-adapter-luxon and luxon as dependencies in order to test also the time axis
