Issue Summary

When creating a new repository, the default suggestion for the main branch is 'main'
However, if you don't give it a name and after the repository is created the main branch name defaults to 'Master'

According to this post, we should have moved away from the 'Master' terminology

Steps to Reproduce

1. Create a new repository
2. Go through the normal steps (Select a workspace, give it a name, assign it to a project)
3. Leave the "Default branch name" field blank
4. Click Create repository

Expected Results

• The main branch should be named 'Main'

Actual Results

• The main branch is named 'Master'

Workaround

• Don't leave the "Default branch name" field blank. Give it a name
