FIPS Compatibility Issue

### Have you read the Contributing Guidelines on issues?

- [x] I have read the [Contributing Guidelines on issues](https://github.com/facebook/docusaurus/blob/main/CONTRIBUTING.md#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.
- [x] I have tried creating a repro with https://new.docusaurus.io.
- [x] I have read the console error message carefully (if applicable).

### Description

I have a requirement to build my Docusaurus website in a FIPS compliant container. Currently it is not possible as Docusaurus [hardcodes the use of the md5 algorithm](https://github.com/facebook/docusaurus/blob/main/packages/docusaurus-utils/src/hashUtils.ts) .

Could it be possible to use another hashing algorithm that is [compliant to FIPS 140-2](https://csrc.nist.gov/files/pubs/fips/140-2/upd2/final/docs/fips1402annexa.pdf) (or a customisable one) like sha256?

Are you only using md5 a hashing function or does it have some cryptographic use also?

I attempted to use [patch-package](https://www.npmjs.com/package/patch-package) to modify my node_modules & replace md5 with sha256 in the hashUtils module. This wasn't successful and resulted in further issues i was unable to debug.

### Reproducible demo

https://github.com/bendudz/docusaurus/tree/fips-repro/examples/classic

### Steps to reproduce

The repro uses a publicly available .FIPS image. If you have access to [Chainguard](https://images.chainguard.dev/directory/image/node-fips/overview) there are images available from them that could be substituted into the dockerfile FROM clause.

Clone the repro & navigate to the example.

`cd examples/classic`

Build the dockerfile

`docker build -t fips-repro --no-cache=true .`

### Expected behavior

I would like to think Docusaurus could be built in a FIPS compliant manner with either an applicable algorthim used or a customisable option to replace md5.

### Actual behavior

Attempting to build the site in the FIPS enabled container ends up with a long stacktrace.

```shell
/opt/app-root/src # npm run build
