chore: Add tokenless v3 example

Notable Changes

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. In 2022 this entity acquired Codecov and as result Sentry is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Closing this as we won't be turning on tokenless v3 for codecov org so we'll need to put this example in a different org. For tokenless v3 in the bundlers repo testing, we can add to the integration tests in a separate effort
