## Summary of the Pull Request
This updates defaults.json to include the default values for all global and profile settings. Most default keybinding args are added too. This also updates a few outdated items found in the docs.
## PR Checklist
* [X] Closes#5189
## Validation Steps Performed
After making the changes, I made sure all of the settings are deserialized by debugging and stepping through the `LayerJson` code.
- [X] Global Settings
I was mainly looking for two things:
- the key/value pair is found and read
- the value did not change before/after the pair was read
