Relevant Issues

resolves #4582

What is in this change?

This PR

1. Adds patch-package as a dependency inside /collector, an NPM package that allows for easy patching of code inside node_modules.
2. Sets up patch-package as a yarn postinstall script inside package.json
3. Applies a simple fix in the epub2 library to the EPub class to ensure title is a string before calling .trim()

Additional Information

Yarn has native lifecycle scripts, one of which is called postinstall which runs after packages are added, removed, etc. Read more here.

The postinstall script this PR adds calls patch-package, which looks at the patches directory and applies the git diffs it discovers inside there.

Example Execution Flow

1. yarn install or yarn is executed
2. Dependencies are installed
3. postinstall script is executed which runs patch-package
4. patch-package applies git diffs inside the relative patches directory to code in node_modules

Developer Validations
