Fedora CoreOS next stream rebased to Fedora Linux 35

[Dusty Mabe]

Hi all,

Fedora Linux 35 Beta was released today [1]. Our Fedora CoreOS `next` stream
has been migrated to Fedora Linux 35 content. Existing nodes on the `next`
stream will update as normal over the following days. Please test it out and
report any issues in our issue tracker [2].

Thank you to everyone helping find issues by running the `next` stream!
