feat: expectjsonlength enhancement

[leelaprasadv]

closes #290

Support pactum matchers in expectJsonLength assertion.

Changes:

• Allow pactum-matchers on expectJsonLength
  • allowed matchers - gte, lte, lt, gt. notEquals
• semver vulnerability fix - updated via npm audit fix
• Bump version to 3.5.1

Examples

const { spec } = require('pactum');
const { gte, lte, lt, gt } = require("pactum-matchers");

await spec()
  .get('https://reqres.in/api/users')
  .expectJsonLength('data', lte(6));

const { spec } = require('pactum');
const { gte, lte, lt, gt } = require("pactum-matchers");

await spec()
  .get('https://jsonplaceholder.typicode.com/users')
  .expectJsonLength('.', gte(10));
