[docker] Install less (#5677)

Browse source 
I was unable to fully use pry using the docker version of dev.to.
For instance while trying to examine certain variables or trying to use
`caller` to checkout the backtrace, I would run into the a `multi-call binary error` with
`BusyBox`.

On looking up this error, discovered https://github.com/pry/pry/issues/1248 which also
had the fix which was simply to install less for the docker image.

Verified locally that pry's full functionality works.
