fix: crash in HeaderParser in dicer. (#15963)

Resolves [Dependabot Alert
74](https://github.com/twentyhq/twenty/security/dependabot/74).

Upgraded `graphql-upload` from `13.0.0` to `16.0.2`. Type exports
changed. API remains the same.

Tested the following upload flows:
- profile picture
- workspace logo
- rich text editor (image, video, file)
- record profile picture
- file associated to record.

They all work as intended, nothing breaks.
