Installing vim in base image

[prayagsingh]

Hello @saghul, Is there any specific reason for installing vim in the base image? ref: https://github.com/jitsi/docker-jitsi-meet/blob/81dc3849b18b734ea20c8ed9281df14353615603/base/Dockerfile#L24

That is k Lu the case for unstable images, because they are mainly used for testing, and it's useful when debugging stuff. We could perhaps replace it with vim-tiny to make images a tad smaller.
