Could we unify oktetoErrors.ErrManifestNotFound and discovery.ErrManifestNotFound? I think it can be error-prone to have both

Agree with unifying both errors if they are used to represent the same. Also, careful with the error handling if we do the change

[ifbyol]

Can we run the E2E before merging it?

i remember going thought this with #2969 can we check this case is covered with this change?
