[v3 backport] Oras v2 v3 backport with http fallback

**What this PR does / why we need it**:

Update oras v2 which removes many unwanted dependencies.

**Special notes for your reviewer**:

This PR has two commits. The first is the commit from the [helm v4 PR ](https://github.com/helm/helm/pull/13382) and the second is some code to automatically fallback to http which was added to not break current v3 behavior.

**If applicable**:
- [ ] this PR contains user facing changes (the `docs needed` label should be applied if so)
- [ ] this PR contains unit tests
- [ ] this PR has been tested for backwards compatibility


connyay: We (@tanium) are hitting some pains where our internal registry is returning 500s randomly when fetching oauth tokens and this PR would dramatically improve our lives with `retry.NewTransport(transport)`. Would love to see this land 👍 

Thank you @TerryHowe 👏
