Form-data security update for 4.x.x

I noticed that chai-http 4.4.0 has a security vulnerability stemming from form-data@4.0.2. It's fixed via form-data@4.0.4. I'm curious if there's interest in others of updating chai-http@4 to update form-data? I'd be happy to take a look if maintainers are interested. I've investigated updating chai to 5.x.x but thought this could be a good short-term improvement without doing major refactors and other package updates like chai datetime. ``` ├─┬ chai-http@4.4.0 │ └─┬ superagent@8.1.2 │ └── form-data@4.0.2 ```
