There is a beta of fish shell 4.0 which is based on rust. How can I install it?

I found a repo for Fedora 41 here. I have added it to /etc/yum.repos.d and it appears when I run rpm-ostree upgrade --check but no upgrade happens.

Manually installing the .rpm file reports a version conflict.

Install rust and sphinx via brew.
Run the cargo install command listed on the fish shell GitHub with the tag 4.0b1.
Run the install.sh script and then copy the fish binaries (there are 3) to ~/.local/bin
Point your terminal to said binaries.
