Add CI workflows to enhance the dev experience

[umbynos]

Add some checks workflows to this repo to enhance the developer experience and to catch common problems:

• 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
• https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-license.md
• https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-markdown-task.md
• https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-taskfiles.md

@umbynos @MatteoPologruto. I have already prepared the work for https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-go-dependencies-task.md last year, but have been blocked on its completion waiting for an answer to a question. See #7218 in the internal issue tracker for details.

The other workflows will be super valuable additions to the project though.

Thanks so much for your excellent work Matteo.

Since we already have a dedicated issue in the internal tracker for adding the remaining workflow, I will close this as resolved.
