## Context
Resolves FE-2923
There's an issue with creating s3 keys in the storage settings at the
moment, where naming your key throws a form field validation error. This
PR fixes that - not sure when this was introduced though, but the main
fix was just using `field` from `render` instead of calling `register`
## To test
- [ ] Verify that you can create an s3 access key via the storage
settings
