Subject: [PATCH] fix: show API error message when an error occurs during
 branch creation (#44638)

## Problem

When a user creates a branch but their GitHub account does not have
access to the repo, the UI shows a generic branch not found message.

## Solution

The API actually returns a more detailed message. Show it instead of the
generic one.

## Summary by CodeRabbit

* **Bug Fixes**
* Fixed error message handling when creating branches from invalid Git
references. Users will now receive appropriate error messages when
attempting to use a non-existent branch.
