aws_stepfunctions: JsonPath.arrayContains errors when checking for booleans

[Pharrox]

Describe the bug

Using JsonPath.arrayConains throws an error when trying to check if an array contains a boolean value because the inner function for rendering expressions doesn't account for boolean values:

JsonPath.arrayContains(JsonPath.entirePayload, true);

Expected Behavior

Renders the intrinsic function as;

States.ArrayContains($, true)

Current Behavior

Throws the error:

Error: Unxexpected value.
    at renderInExpression (./aws-cdk-lib/aws-stepfunctions/lib/private/json-path.js:1:5194)
    at Array.map (<anonymous>)
    at Function.arrayContains (./node_modules/aws-cdk-lib/aws-stepfunctions/lib/fields.js:1:2527)
...

Reproduction Steps

Run anywhere in a Typescript CDK app:

JsonPath.arrayContains(JsonPath.entirePayload, true);

Possible Solution

Update renderInExpression to be able to identify and output boolean values.

Probably along the lines of adding:

if (typeof x === 'boolean') return x.toString();

Additional Information/Context

Could probably occur in other intrinsic functions. Any intrinsics that uses renderInExpression seems like it would suffer from this problem.
