Cannot Import OAS from 'Fetch in Bruno'

JIRA

I have checked the following:

• I have searched existing issues and found nothing related to my issue.

This bug is:

• making Bruno unusable for me
• slowing me down but I'm able to continue working
• annoying
• this feature was working in a previous version but is broken in the current release.

Bruno version

3.0.1, 2.15.0

Operating System

Mac 15.5

Describe the bug

Fetch in Bruno for OAS launches a separate modal Import OpenAPI Spec which then errors out with Unknown collection format.

However, if you take that same URL and enter it in the Import Collection modal, it works.

.bru file to reproduce the bug
