Add zod to the benchmark

[ilanashapiro]

Addresses issue #66

zod is quickly growing in popularity as a json-schema validator. It is now added to the benchmark so it can be compared with the other validators.

Result of running node index.js in the terminal (zod is highlighted). I commented out the part of the code that limits the logging to the top 6 results, so that all validators are shown for comparison. Also note that the current sorting (which I did not modify) is from least to greatest number of failing tests.

Thanks Ilana! Would you mind updating the PR description with a second screenshot, showing how zod compares against others in the benchmark on your laptop?

@ChALkeR oh my apologies, never mind then, I was looking through the commit history for this repo and I thought you were added as a collaborator with write access. If you do know of someone with write access that could review this, it would be great if you could link them. Thanks!
