Finalize repo QA compliance

[BTT21000]

As part of the TM issue https://github.com/api3dao/tasks/issues/849 for QA, some requirements need to be addressed:

Repo setup requirements as per new_repo_creation_checklist.md:

• Write a short description for the repository in the description field
• Link to some relevant page if applicable (e.g. api3 docs, npm package link, ...)
• Review the renovate.json configuration file to ensure it satisfies with our dependency management strategy and include owner(s) as reviewers.
• Add the relevant license file (LICENSE.md) consistent with the organizational standards or project requirements.
