:sparkles: Added unaliasing to pattern setup

[polyglotdev]

In the process of setting up patterns, we've added a step to unalias any existing alias with the same name. This ensures that our dynamically defined functions won't conflict with any pre-existing aliases.

What this Pull Request (PR) does

During the setup of fabric I added the obsidian vault bits and received this error after sourcing my ~/.zshrc

 (eval):2: defining function based on alias `agility_story'
    (eval):2: parse error near `()'
    (eval):2: defining function based on alias `ai'
    (eval):2: parse error near `()'
    (eval):2: defining function based on alias `analyze_answers'
    (eval):2: parse error near `()'
    (eval):2: defining function based on alias `analyze_cfp_submission'
    (eval):2: parse error near `()'
    (eval):2: defining function based on alias `analyze_claims'
    (eval):2: parse error near `()'
    (eval):2: defining function based on alias `analyze_comments'
    (eval):2: parse error near `()'
    (eval):2: defining function based on alias `analyze_debate'
.... cut for brevity

The unalias "$pattern_name" 2>/dev/null command removes any existing alias with the same name as the function you're about to define. The 2>/dev/null part suppresses any error messages if the alias doesn't exist, ensuring the script runs smoothly.
