Incorrect version of Requests dependency loaded

I've been working through various PHP 8.1 related issues, and one thing I noticed is that due to a dependency is this module, WordPress core loads an incorrect version of the Requests library:

```
[327] => /usr/src/app/wordpress/wp-includes/class-wp-http.php
[328] => /usr/src/app/vendor/rmccue/requests/library/Requests.php
```

This is because `class-wp-http.php` calls `class_exists` on `Requests`, causing the autoloader to kick in and load the one from vendor, instead of the version shipped with WordPress core. The dependency comes from:

* altis/dev-tools -> lucatume/wp-browser
* lucatume/wp-browser -> wp-cli/wp-cli
* wp-cli/wp-cli -> rmccue/requests

Acceptance criteria:

- [ ] WordPress should load the Requests library bundled with Core
