setup_container_runtime.sh: refresh bash path after podman removal

If we remove podman in the "Found a very old podman; removing" function, we subsequently run `command -v podman` later in the script but we're hitting a stale cache.

e.g.,

```
+ setup_container_runtime
++ id -nu
+ loginctl enable-linger jenkins-build
+ command -v podman
/usr/bin/podman
+ podman system info
++ podman version -f '{{ lt .Client.Version "4" }}'
+ '[' true = true ']'
+ echo 'Found a very old podman; removing'
Found a very old podman; removing
+ command -v dnf
+ command -v apt
/usr/bin/apt
+ sudo apt remove -y podman

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
