[Q] usage with TypeScript and webpack 5 (CRA 5.0.1)

We had exceljs working with our old webpack/CRA v4 setup that looked like this:

```
// tsconfig.json
{
"compilerOptions": {
"target": "ES2020",
"lib": ["dom", "dom.iterable", "esnext", "webworker"],
"allowJs": true,
"skipLibCheck": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"strict": true,
"forceConsistentCasingInFileNames": true,
"noFallthroughCasesInSwitch": true,
"noImplicitAny": true,
"module": "esnext",
"moduleResolution": "node",
"resolveJsonModule": true,
"isolatedModules": true,
"noEmit": true,
"jsx": "react-jsx",
"outDir": "./built",
"typeRoots": ["./typings", "./node_modules/@types"]
},
"include": ["**/*", "typings"],
"paths": [
{
"exceljs": "node_modules/exceljs/dist/exceljs.bare.min.js"
}
]
}
```

```
// craco.config.js
module.exports = {
devServer: () => {
// ...
},
webpack: {
configure: (webpackConfig) => {
// ...
webpackConfig.resolve.alias.exceljs = 'exceljs/dist/exceljs.bare.min.js';
return webpackConfig;
},
};
```

After updating CRA to 5.0.1 we now get an error saying:

```
ReferenceError: process is not defined
at Readable.on (_stream_readable.js:763:1)
at createReadableStreamAsyncIterator (async_iterator.js:177:1)
at Readable. (_stream_readable.js:922:1)
at M.read (xlsx.js:251:1)
at parseXLSX (excel.ts:313:1)
at async submitMetadata (foo.tsx:151:1)
```

Do we need to change anything with the setup? How do we get this working with webpack 5?
