Fix build due to invalid default Settings

[misha]

As mentioned in #274, a file was preventing an errror-less build because an experimental setting was missing. I supplied a default value for the field.

However, upon fixing it I found that the underlying type Settings had been compiled with some previous version of the type that failed to includes the following properties:

1. showPixelEquivalents
2. rootFontSize

The file that declares the type, state.ts, was already updated to hold those properties, so I re-built the language server. This fixed the two fields above, but the experimental setting was gone this time. To fix the final error, I added that field to the original type definition in state.ts.

Likely to completely fix this, you would need to re-release the language server and update the extension's version.

Bumped into this too, waiting a long time to get this fixed

Hey @misha. Sorry for the delay. I don't think this is relevant anymore, but thanks anyway! 🙏
