Timeouts/failures when installing other Ruby versions

[henryaj]

When attempting to install other Ruby versions in the environment setup script (by running rbenv install), I find the setup just times out.

Are there any quick fixes for this? Wondering if it might be better to tell the agent to do the setup within the task (e.g. by adding an instruction to AGENTS.md) to avoid whatever issues/timeouts are occurring during the container setup step.
