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, web page, ...)
• Add/remove relevant team members as collaborators (e.g., technical team, technical management members) within the repo (e.g. Steffi is no longer working on this project)
• Grant write permissions to the appropriate team members.
• Enhance README.md files if needed with essential high level information about the project and its scope.
• Add the relevant license file LICENSE consistent with the organizational standards or project requirements.
• Initialize a CONTRIBUTING.md file if applicable if the project is open to contributions from outside developers, providing guidelines for contributions.
• Install Renovate in the repository, following the guidelines outlined in dependencyManagementStrategy.md.
• Create a renovate.json configuration file in the root of the repository to manage dependencies effectively, as per our dependency management strategy.
• If applicable, set up Renovate for automated security vulnerability scanning to detect vulnerabilities in the codebase.
