🎁Enhancement: Dotnet user secrets

[GustavEikaas]

Expose some way to load secrets.json into a buffer.

e.g require("csharp").load_secrets() Will prompt which project to open secrets for with a selector. When choosing one, resolve the file and load into a new buffer

I made myself a small and really barebones telescope extension for this. If anyone is interested I can share it.
