Pre-submission checklist for maintainer updates (delete this if you're updating a different file)

If you're adding a new maintainer to the CSV file, please review each of these actions as well:

• The maintainer has also created or updated their LFX Individual Dashboard profile.
• You've also sent an email with the addresses to [email protected] for access to Service Desk and mailing lists.
• Optional: You've also sent a PR with affiliation updates to cncf/gitdm.
