docs: Add MacOS runners debugging guide and SSH access instructions
This MR adds a new debugging guide for MacOS runners and adds SSH instructions to the existing access documentation.
- Creation of a new
debugging.mdfile with some guidance for debugging AWS MacOS runner instances (more will be added in subsequent MRs) - Addition of detailed SSH access instructions in the
access.mdfile, explaining the two-step process of connecting through runner managers - Updates to the main MacOS README to reference the new debugging documentation
- A typo fix
The debugging guide includes information on monitoring instance health through AWS dashboards, checking metrics, and locating important log files.
Note: I'll be adding more sections and details in subsequent MRs
