feat: make oci manifest version configurable

[thepabloaguilar]

Hi! I'm opening this PR to fix that issue with AWS ECR, when using the OCI Manifest Version 1.1 I receive an error from AWS but when setting to version 1.0 everything works as expected!

So I make it configurable keeping the current using version as default! I searched a bit the code to see if flipt could have any impact on letting the users choose between versions and the answer is no, flipt won't use the newly added field (on 1.1 version) subject! If you want to compare: v1.0.2 abd v1.1.0

Other people are having the same impact:

• Oras 1.1.0 breaks AWS ECR uploads oras-project/oras#1133
• oras attach failing for registries that don't support 1.1-RC image media type oras-project/oras#1224

Fixes #2907

Thanks for discovering and fixing this @thepabloaguilar !

Just a couple comments on here, otherwise, it looks great.
We can get this in a patch release for you 👍

[thepabloaguilar]

Done @GeorgeMac!

[markphelps]

looks good to me! thanks @thepabloaguilar !

Im guessing we should document this as well in our configuration docs?

[thepabloaguilar]

Sure @markphelps! I'd document putting a note or smth saying the problem with AWS and it can happen for other providers.

And I think we forgot to document the allowed_teams on here: Configuration - Overview - Authentication Methods: GitHub
