Do not transform static JS assets

Have you read the Contributing Guidelines on issues?

• [X] I have read the Contributing Guidelines on issues.

Prerequisites

• [X] I'm using the latest version of Docusaurus.
• [X] I have tried the npm run clear or yarn clear command.
• [X] 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.
• [X] I have read the console error message carefully (if applicable).

Description

Static assets ending in .js seem to be modified in a docusaurus build.

Reproducible demo

No response

Steps to reproduce

Create a new Docusaurus project.

npx create-docusaurus@latest my-website classic --typescript
cd my-website

Create a static asset containing some JavaScript.

echo "let a = 1; let b = 2;" > ./static/example.js

Build and serve the project.

npm run build
npm run serve

Open localhost:3000/example.js in your browser and observe that the content served by the browser does not look like the original file anymore, but like this.

let a=1,b=2;

This does not happen when renaming the file to use a different extension, such as .txt.

Expected behavior

I would expect Docusaurus not to modify the contents of static .js assets.

Actual behavior

Docusaurus actually transformed the asset.
