Add syntactic content assistance to the filter field

[glaslos]

This is a feature of chevrotain, documentation is here
I don't think we need to be concerned regarding the performance but have a look at the related section in the documentation.

Hello @glaslos

This feature may be deprecated in Chevrotain in the future.
Perhaps you should have a look at https://langium.org/ to help build language service.

• Its using Chevrotain under the hood...

Thanks for the heads up, I will have a look

Can we close this issue if not needed @glaslos ?
Or I would like to work on this

Enhanced syntactic content assistance using Chevrotain, which is already integrated as the base parser. We may refactor to Langium (https://langium.org/) in the future.
