Tree views in current branch/workflows/settings is sorted by repo name length

**Describe the bug**
This is an _unexpected_ behavior. The order of the items in the tree views are sorted by _the length of the repository name_. This is an unreasonable sorting strategy! 😅

**To Reproduce**
Steps to reproduce the behavior:
1. Login
2. Look at the workflows

**Expected behavior**
I expect the workflows to be sorted by some _reasonable_ means like a) alphabetically or b) order appearing the workspace. The easiest would be just alphabetically. Finding the correct repository workflow now is hard. I need to think about how _long the name of the repository is_ 🤯

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Extension Version**
`v0.26.2`

Start by locating the tree-view implementation for Current Branch, Workflows, and Settings in this VS Code extension, then trace how repository names are ordered. Change the ordering to alphabetical as requested and verify the affected views, especially Workflows, no longer sort by repository-name length.
