docs: ✏️ Added missing code block

[alejandrosaenz117]

Type of change

• A new feature
• A bug fix
• Documentation only changes
• Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
• A code change that neither fixes a bug nor adds a feature
• A code change that improves performance
• Adding missing tests or correcting existing tests
• Changes that affect the build system or external dependencies
• Changes to our CI configuration files and scripts
• Other changes that don't modify src or test files

Added missing code block after the m1/m2 section that was causing the rest of the README to be in a code block
