feat: support tv4 as a inbuilt lib

[poojabela]

Description

Added tv4 as a built-in library in Bruno to support JSON Schema validation in scripts.

Example usage in Bruno scripts:

const tv4 = require("tv4")

const schema = {
  type: 'object',
  properties: {
    name: { type: 'string' },
    age: { type: 'number' }
  }
};

const isValid = tv4.validate(res.getBody(), schema);
console.log('Validation result:', isValid);
if (!isValid) {
  console.log('Validation errors:', tv4.error);
}
