fix(cloudformation-diff): format test

[ChakshuGupta13]

Reason for this change

Currently, yarn build fails in '@aws-cdk-testing' package with following error because 'Received' string is formatted with chalk.red and 'Expected' string is by default formatted with chalk.green:

   ✖  @aws-cdk/cloudformation-diff:test
$ cdk-test
       FAIL  test/format.test.ts
        ● format value can handle partial json strings

          expect(received).toEqual(expected) // deep equality

          Expected: "{\"nice\":\"great\",\"partialJson\":\"{\\\"wow\\\": \\\"great\"}"
          Received: "{\"nice\":\"great\",\"partialJson\":\"{\\\"wow\\\": \\\"great\"}"

            6 | test('format value can handle partial json strings', () => {
            7 |   const output = formatter.formatValue({ nice: 'great', partialJson: '{"wow": "great' }, chalk.red);
          > 8 |   expect(output).toEqual('{\"nice\":\"great\",\"partialJson\":\"{\\\"wow\\\": \\\"great\"}');
              |                  ^
            9 | });

            at Object.<anonymous> (test/format.test.ts:8:18)

Description of changes

As unit-test aims to test equality of strings in terms of content instead of color formatting, hence, it is better to utilise toMatch instead of toEqual.

Description of how you validated changes

Upon retesting, unit-test passed:

 ✔  @aws-cdk/cloudformation-diff:build  [local cache]

Exemption Request

Reason: Change has been made to unit-test and not source, hence, change to an integration test file does not make sense:

❌ Fixes must contain a change to an integration test file and the resulting snapshot.
