Coarse-grained confidence level of how well a particular finding
satisfies the criteria to match a particular infoType.
Likelihood is calculated based on the number of signals a finding
has that implies that the finding matches the infoType. For example,
a string that has an '@' and a '.com' is more likely to be a match
for an email address than a string that only has an '@'.
In general, the highest likelihood level has the strongest signals
that indicate a match. That is, a finding with a high likelihood has
a low chance of being a false positive.

works, see Match

Values:
LIKELIHOOD_UNSPECIFIED (0):
Default value; same as POSSIBLE.
VERY_UNLIKELY (1):
Highest chance of a false positive.
UNLIKELY (2):
High chance of a false positive.
POSSIBLE (3):
Some matching signals. The default value.
LIKELY (4):
Low chance of a false positive.
VERY_LIKELY (5):
Confidence level is high. Lowest chance of a
false positive.
