Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io. (Can repro on StackBlitz; CodeSandbox filters apostrophes.)
• I have read the console error message carefully (if applicable).

Description

For example, creating a file called "Beginner's Guide.md" causes it to be written to registry.js verbatim:

So, we obviously have a syntax error there.

Reproducible demo

No response

Steps to reproduce

1. Create a file with an apostrophe in it's name, such as "Beginner's Guide.md"
2. Run npm start

Expected behavior

The apostrophe would be escaped.

Actual behavior

The apostrophe is written verbatim.

Your environment

• Docusaurus version used: Whichever the latest one published to NPM is as of 2023-07-20

Self-service

• I'd be willing to fix this bug myself.
