chore: add optum to users list

[tperdue321]

RallyHealth (part of Optum) & Optum are using Argo Rollouts and have features we have created in our fork we would like to contribute back upstream if the community wants them. First, we need to add ourselves to the User list!

Checklist:

• Either (a) I've created an enhancement proposal and discussed it with the community, (b) this is a bug fix, or (c) this is a chore.
• The title of the PR is (a) conventional with a list of types and scopes found here, (b) states what changed, and (c) suffixes the related issues number. E.g. "fix(controller): Updates such and such. Fixes #1234".
• I've signed my commits with DCO
• I have written unit and/or e2e tests for my change. PRs without these are unlikely to be merged. N/A
• My builds are green. Try syncing with master if they are not.
• My organization is added to USERS.md.
