[docker]Fix the problem of missing dependencies less (#5034)

Fixes https://github.com/apache/pulsar/issues/4957

Master Issue: https://github.com/apache/pulsar/issues/4957

### Motivation

Currently, when packaging the docker image, the dependency less is lost, resulting in the following exception being thrown when presto SQL is running
```
Cannot run program "less": error=2, No such file or directory
```

### Modifications

* Add dependency less
