What I did

Improved DL3009 rule to properly handle all apt-based package managers:

• Added support for apt and aptitude in hasUpdate function
• Updated error message to be more specific about tools and path

How I did it

1. Enhanced the hasUpdate function to detect update operations from apt and aptitude commands
2. Updated the error message to clearly specify which package managers it applies to and the exact path that needs cleaning

How to verify it

Create a test Dockerfile with different apt-based package managers:

FROM ubuntu:20.04

# This will trigger DL3009 (apt-get)
RUN apt-get update && apt-get install -y python3

# This will also trigger DL3009 now (apt)
RUN apt update && apt install -y curl

# This will also trigger DL3009 now (aptitude)
RUN aptitude update && aptitude install -y wget

# This will not trigger DL3009 (proper cleanup)
RUN apt-get update && apt-get install -y git && rm -rf /var/lib/apt/lists/*

Run hadolint on the file:

hadolint Dockerfile

The first three RUN instructions should now trigger the DL3009 warning with the updated message.
