Formatting numbers in the validateNumber validator

[joeo73-impinj]

In my en-us.yaml I have the following line:

lessThanOrEqualTo: '{description} must be less than or equal to {lte}'

In my use case, the LTE (or GTE) can be quite large: > 1,000,000.

Is there a way to get the {lte} placeholder value formatted with separators?
