If have silk touch pick, then use it on glowstone

## Describe your suggestion
I set Baritone to auto-mine glowstone, and it chose to break it with fish/fists instead. Breaking with a silk touch pickaxe would be much more preferable in 90% of situations

## Settings
Allow/Disallow silk priority

## Context
Self explanitory

## Final checklist
- [owo] I have not used any OwO's or UwU's in this issue.

Start by tracing Baritone's auto-mine behavior for glowstone and how it selects a tool. Clarify how an “Allow/Disallow silk priority” setting should work, then verify that auto-mining uses a silk touch pickaxe when available and preserves the existing behavior when it is not.
