Description of problem:

fedora-toolbox:f34 still points to Rawhide, even though f34 has already been branched.

I use toolbox on regular Fedora 33 with fedora-toolbox images. In order to perform some packaging work, I needed a f34 environment. As far as I understand, this should give me that:

    $ toolbox create --container fedora-34 --release f34
    Created container: fedora-34
    Enter with: toolbox enter fedora-34
    $ toolbox enter fedora-34
    ⬢$ 

So a container was created. But I got Rawhide instead of branched f34:

    ⬢$ ls /etc/yum.repos.d/
    fedora-rawhide.repo
    ...

How reproducible:
Always

Steps to Reproduce:
1. toolbox create --container fedora-34 --release f34
2. toolbox enter fedora-34
3. ls /etc/yum.repos.d/

Actual results:
Rawhide repositories listed

Expected results:
Fedora 34 repositories listed

Additional info:

Relevant part of `toolbox list`:

    $ toolbox list

Checking from registry.fedoraproject.org, f34/fedora-toolbox:34 has been last updated on 2020-10-07 [1]. There is also another image called fedora-toolbox:34, which is much more recent. I do not understand the different, or why I get the older one by default.

It is unclear to me what would be correct way to use Toolbox for Fedora release development and packaging.
