Godot Editor always tries to modify `editor/theme.tres`.

In my case, Godot editor always tries to change `Color` in `editor/theme.tres`, which makes the submodule dirty.

I searched for a solution but couldn't find a good solution.

If the repository owner has changed the `interface/inspector/default_float_step` setting, it may be a good idea to restore it to the default and continue development.

Or maybe changing the repository to include `.res` instead of `.tres` would solve the problem, but I'm not sure.

I reported it, but it's not a serious issue so you can probably ignore it.
