Add reference to Intuit creating the project

[caniszczyk]

CNCF website guidelines allow for referencing the original creator of the project: https://github.com/cncf/foundation/blob/main/website-guidelines.md

For example, Envoy created by Lyft

It would be nice to see Intuit there was an end user driven open source project.

Thanks for the suggestion @caniszczyk. It's actually already mentioned on the website if you scroll down to the bottom of the page along with the list of maintainers: https://argoproj.github.io/
