feat: shuffle test suite order in run command

[NivYarmus]

Motivation/Description of the PR

Hello there.
Added an option to the run command that shuffles the order in which test suites are run.
Helpful if you want to make sure that your tests are not passing just because of a lucky side effect of a previous test.

• The shuffle functionality lacks test coverage. Consider adding tests to verify that when the shuffle option is enabled, the test files are randomized while maintaining the same set of files.
