Add automatic gh auth login prompt when sharing results

- Modified setup_github_authentication to offer interactive gh auth login
- Added auto_login parameter to control whether to prompt for authentication
- If gh is not authenticated, prompts user to run gh auth login
- Runs gh auth login interactively if user agrees
- Updated share_results to pass through auto_login parameter
- Falls back to saving results locally if authentication fails or is skipped

This makes sharing results much easier - users no longer need to manually set up authentication beforehand. The function will guide them through the process when needed.

 Share your benchmark results with the LinearSolve.jl community to help improve 
 automatic algorithm selection across different hardware configurations.
 
 This function will authenticate with GitHub (using gh CLI or token) and post
 your results as a comment to the community benchmark collection issue.
 
-# Setup Instructions
+If authentication is not found and `auto_login` is true, the function will
+offer to run `gh auth login` interactively to set up authentication.
+
+# Arguments
+- `results`: AutotuneResults object from autotune_setup
+- `auto_login`: If true, prompts to authenticate if not already authenticated (default: true)
+
+# Authentication Methods
+
+## Automatic (New!)
+If gh is not authenticated, the function will offer to run authentication for you.
 
 ## Method 1: GitHub CLI (Recommended)
 1. Install GitHub CLI: https://cli.github.com/
