[AWS::WAFv2::WebAC] - [BUG] - UNABLE to go lower than value 100 for "RateBasedStatementProperty"

[urda]

Name of the resource

AWS::WAF::WebACL

Resource Name

AWS::WAFv2::WebACL

Issue Description

I am unable to set my limit for a RateBasedStatementProperty below 100. Attempting to do so results in a stack error:

Resource handler returned message: "Model validation failed (#/Rules/0/Statement/RateBasedStatement/Limit: failed validation constraint for keyword [minimum])" (RequestToken: TOKEN, HandlerErrorCode: InvalidRequest)

Expected Behavior

I am able to set a rate below 100.

Observed Behavior

Unable to set a rate below 100, must be done via web console in AWS.
