Add list of collaborators to asf.yaml

[yashmayya]

• ASF Infra allows Apache projects to assign the GitHub "triage" role (see permissions for each role here) to up to 10 "collaborators" (non-committers) per repository.
• This allows for things like assigning, editing, and closing issues / PRs (without giving write-access to the code) and also adding / removing labels, requesting PR reviewers etc.
• This has been adopted by various other Apache projects and is pretty useful as it allows non-committers to contribute additionally towards project maintenance activities.
• In the Apache Kafka project, a policy was adopted to add the top 10 non-committer contributors from the past year (as per git shortlog) as collaborators and has been fairly successful. This PR is a proposal to adopt the same policy for the Apache Pinot project.
• The collaborator list will be updated periodically to account for changes in contribution levels as well as collaborators potentially becoming committers.
