Fix/remove argument-parser

[griffin-stewie]

Summary

Remove the executable "markdown-tool" from the product so that ArgumentParser is not added unnecessarily when used it as a library.

In my case, I added swift-markdown to my CLI tool that it uses swift-argument-parser v1.0.1 then I got the following error.

Dependencies could not be resolved because root depends on 'swift-argument-parser' 0.4.4..<0.5.0 and root depends on 'swift-argument-parser' 1.0.0..<1.1.0.

This PR will fix this issue.

Dependencies

none.

Testing

All tests passed my local environment.

Thanks for this! It looks like this shared some overlap with #13 - would you mind reworking this on top of the current main branch?

@QuietMisdreavus
Thank you for reviewing my pull request.

I went over the current status of the main branch and what we wanted to do. Many of the changes I added were already included in the main branch, so they turned out to be simple changes.

Please review this pull request.

@griffin-stewie Thanks for doing this! Do you mind updating the base Package.swift while we're at it here? I think we should try to keep them consistent as much as possible.
