feat(docs): add make troubleshoot target

[Aditi-24-05]

Summary

Adds a make troubleshoot target to the Makefile as requested in #38.

Running make troubleshoot prints a numbered, terminal-friendly index of all sections from docs/troubleshooting.md, each followed by a one-line tip extracted from the first ### sub-heading under that section.

Changes

• Makefile : new .PHONY: troubleshoot target under a # ---Docs ---- section
• CONTRIBUTING.md : added make troubleshoot row to the Running checks locally table

Output

$ make troubleshoot
