Support Brave browser in create-release-branch --interactive

[georgewrmarshall]

Description

The @metamask/create-release-branch package (v4.1.1) currently doesn't support Brave as a default browser when attempting to open the release UI, causing the release process to fail. We need to add support for Brave browser to ensure the release workflow works correctly for all team members.

Technical Details

• Current error occurs in the open package dependency when trying to launch the UI server
• Error message: Error: Brave is not supported as a default browser
• The issue appears when running yarn create-release-branch --interactive
• The UI server successfully starts on port 3000 but fails when attempting to open the browser

Acceptance Criteria

• create-release-branch should successfully recognize Brave as a supported browser
• The release UI should open in Brave browser when it's set as the default
• If Brave is not supported, it should gracefully fallback to another supported browser
• Update documentation to reflect browser support status

References

• Current @metamask/create-release-branch version: 4.1.1 (from package.json)
• Error log:

We got a similar report from an engineer who wanted to use Arc, so we should consider adding that too.

In addition, perhaps we should catch this error in the future so that at least if people see it, they can always navigate to the page manually?
