Hello.

We encounter an issue where the action fails in the chainctl curl download due to a timeout.

Run chainguard-dev/setup-chainctl@main
Run cd $(mktemp -d)
Downloading chainctl from https://dl.enforce.dev/chainctl/latest/chainctl_linux_x86_64
Error: Process completed with exit code 28.

It is not repeatable/reproducible just a flaky timeout issue.
But when it happens our entire job/pipeline fails, and we try to eliminate such incidents that can be avoided by a simple retry.

Can you please consider adding a retry to the curl to avoid "flakiness"
e.g

this can be as simple as

curl -o ./${out} -fsL --retry 5 "${url}"

or more complicated with configurable values etc...

I can provide a PR if it helps.

Thanks
