Update devcontainer

[rctneil]

Hi,

What's the process to update the devcontainer with your latest releases?

Hi,

Are you facing any issues? Do you have an error log to share?

In my case, whenever I need to change the version of the main container ghcr.io/rails/devcontainer/images/ruby, I need to delete the rbenv volume, but that's because I have mapped the .rbenv folder to use as a cache.

No issues, just wondered how to keep it up to date with what's released here.
