chore: don't output capabilities to Noir Langauge Server output

[asterite]

Description

Problem

There's debug output that goes into the Noir Language Server output:

When debugging the extension using LSP, or just when trying to look into the output of comptime println, that output sometimes gets in the way.

Summary

Removes that debug output.

Additional Context

I wanted to get this done before the next release, because it's a minor thing so it can be done quickly.

PR Checklist
