Avoid False Positives Plugin: ArtifactoryDetector

[gabrielsoltz]

ArtifactoryDetector plugins it's matching what it's expected but also generate false positives when that regexp it's a substring of another string.
By simply adding $ we avoid matching substring and still enforce the starting of the regexp.

Before:
re.compile(r'(?:\s|=|:|"|^)AKC[a-zA-Z0-9]{10,}') Matchs: AKChOBZmLqdWHyGcBssssd7bssskixTgm2E5P7KN/123456
This is a false positive as / is not part of the regexp.

Now:
re.compile(r'(?:\s|=|:|"|^)AKC[a-zA-Z0-9]{10,}'$) No Match: AKChOBZmLqdWHyGcBssssd7bssskixTgm2E5P7KN/123456
re.compile(r'(?:\s|=|:|"|^)AKC[a-zA-Z0-9]{10,}'$) Match: AKChOBZmLqdWHyGcBssssd7bssskixTgm2E5P7KN

If it passes test cases, it looks good enough for me.

FYI @killuazhu if you wanted to chime in.
