Issue Summary

When configuring a Bamboo plan with multiple repositories (e.g., GitHub and Bitbucket), each with different default branches (e.g., main for GitHub (default) and master for Bitbucket), the environment variables ${bamboo_repository_git_branch} and ${bamboo_repository_branch_name} always return master (from Bitbucket), regardless of the default repo set as GitHub.

Steps to Reproduce

1. Create a plan with 2 linked repository
   1. Github > branch > main -->default
   2. Bitbucket > branch > master
2. Configure a task to return environment variables ${bamboo_repository_git_branch}, ${bamboo_repository_branch_name}.

Expected Results

Is expected, that they will have value main, because default repository has branch = main. 

Actual Results

Whereas it always return master branch.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
