feat(docs): create a cheatsheet for ML06 AI Supply Chain Attacks

[shsingh]

• Is there existing cheatsheets at OWASP Cheatsheets
• If there is an existing cheatsheet, does it need updating at the source to cater for machine learning use cases?
• Is there a need for a new cheatsheet topic?
• Add existing or new cheatsheet as a reference to the Top 10 risk document

Example Cheatsheet: Input Validation Cheatsheet

Example of Top 10 risk referencing cheatsheets: ML01 Input Manipulation Attacks - Cheatsheets

adding @mik0w as potential lead to this due to his request for taking lead on the risk document.
