fix: removing our dependency on trim

[erunion]

🧰 Changes

Installing the markdown package throws these warnings from NPM for the trim package:

npm warn deprecated trim@1.0.1: Use String.prototype.trim() instead
npm warn deprecated trim@0.0.1: Use String.prototype.trim() instead
npm warn deprecated trim@0.0.1: Use String.prototype.trim() instead

It seems that we're no longer using trim anymore(?) so I'm removing it from being a dependency.

Before

> npm ls trim
@readme/markdown@7.9.0
├─┬ @readme/markdown-legacy@npm:@readme/markdown@6.87.1
│ └─┬ remark-parse@8.0.3
│   └── trim@0.0.1
└── trim@1.0.1

After

@readme/markdown@7.9.0
└─┬ @readme/markdown-legacy@npm:@readme/markdown@6.87.1
  └─┬ remark-parse@8.0.3
    └── trim@0.0.1

🧬 QA & Testing

All tests were still passing and the dist still gets built fine with npm run build.
