Trufflehog severity hardcoded to 4

[jaguasch]

After running trufflehog task, it was skipped because severity of findings are hardcoded to 4 with ISSUE_SEVERITY at https://github.com/OWASP/glue/blob/master/lib/glue/tasks/trufflehog.rb#L10

code - Trufflehog - #<Set:0x00000001b857a8>
Trufflehog
Problem running Trufflehog ... skipped.
Severity should be between 1 to 3, not 4

Oh snap. I see it support JSON output - we can make it work better via the dynamic task. If that of interest to you, take a look at the docs, and feel free to ping me on OWASP slack for help :) Moving the dynamic will make customization faster and easier...
Otherwise, feel free to open a PR for fixing it.
