[ENHANCEMENT] Notebook with query language to query informations about a project

[d-biehl]

this is just an idea, but I think that can be an interesting option to have a vscode notebook with a simple query language for project informations like defined testcases, keywords, variables, tags and the connection between all these things, like references, where is this keyword called and so on.

Maybe that all that information can be saved in something like a triple store or vector database and can be queried by sematic queries

an example of a query language and a notebook can be found here:
