Config not merged with default

**Describe the bug**
My config file settings are ignored, although a syntax error in that file causes an error.

**To Reproduce**
1. copy the default config file to .config/lazydocker/config.yml
2. restart lazydocker
3. an error occurs : syntax error line xxx
4. remove the typo that causes an error in the sidePanelWidth second comment
6. restart lazydocker
7. the settings are ignored, and the About panel shows the default settings instead of my "lazydocker config merged with the defaults"

**Expected behaviour**
My settings should be merged with the default
