Init command should not create new file when `GitReleaseManager.yaml` exists

[AdmiringWorm]

Description

When calling the init command a new file is being created (GitReleaseManager.yml) even if a configuration file with the old name (GitReleaseManager.yaml) exists.

Expected Behavior

The generation should fail with an existing file exception even when using the old name.

Actual Behavior

A new file is generated.

Possible Fix

Add a check for the old name.

Steps to Reproduce

1. Create GitReleaseManager.yaml
2. run gitreleasemanager init
