add flag for image scanning to use all catalogers rather than just some

[cpendery]

What would you like to be added:
I'd like to have a flag added where an image can be scanned by Syft using all catalogers rather than just a subset.

Why is this needed:
When I create images, I scan them for any vulnerabilities before the build process. I'd like to be able to detect if any files exist that could potentially bring in vulnerable artifacts during the build process.

Additional context:
This is the enhancement required based on #1046 as I had assumed this was default behavior

The new 0.50 version should allow --use-all-catalogers, but it doesn't seem to work on my end?

I should have updated the pr title @LOLCATATONIA. We decided to reuse the --catalogers flag to include all catalogers if you passed in the keyword all. I'll make a pr to make this more clear in the docs/cli
