Subject: [PATCH] bci2: Add defaultBranch keyword argument

Passing the `defaultBranch` argument to `buildContainerImage2()` allows
setting the `latest` for projects where the default branch is not
*main*.  For example:

```groovy
buildContainerImage2(defaultBranch: 'master')
```

This will update the `latest` tag whenever a new build is created on the
*master* branch.
