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:

• Add standard configuration files (e.g. eslint) as per standard requirements and other repositories.
• Install Renovate in the repository, following the guidelines outlined in dependencyManagementStrategy.md.
• Review renovate.json configuration file in the root of the repository to manage dependencies effectively, as per our dependency management strategy.
• Set up Renovate for automated security vulnerability scanning to detect vulnerabilities in the codebase.

Package setup requirements as per new_package_creation_checklist.md:

• If applicable, configure Continuous Deployment (CD) for automated publishing to npm, tailored to the package's release and versioning strategy. This step can include setting up semantic versioning automation and npm publish commands.
• Add relevant package.json fields as applicable (e.g. such that repo links and - in this specific case - keywords show up in NPM, compare this to this)
• Support GitHub Release (e.g. https://github.com/api3dao/chains/releases) as per our standard guidelines (tag releases, changesets such as these, changelogs, and release notes) and integrate CI/CD to support releases through GitHub as applicable.
• Verify the setup of security vulnerability scanning tools (e.g. Renovate) for the codebase and dependencies.
