bring CI up to tooling standard for the arduinoOTA repo

[ubidefeo]

This tool requires proper documentation (README.md) and an up-to-standard CI and standard labelling workflows.
Please @per1234, can you setup things for it?
thank you

Is this done @per1234 ?

There are a couple of standardized workflows that depend on the project being managed as a Go module:

• https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-go-task.md
• https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-go-dependencies-task.md

It's not currently a Go module, so I didn't apply those on the first pass. I think it would be good to do though.

It would also be nice to set up a tester build generation workflow similar to this one:
https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/publish-go-tester-task.md
and perhaps a release workflow as well.
