Rename WORD_WRAP enum to TOGGLE_WORD_WRAP for consistency

[coderabbitai]

Description

Currently, the WORD_WRAP enum in the ACTION_NAME enum doesn't follow the naming convention that indicates it's a toggle action.

For better consistency with other toggle actions (like the proposed TOGGLE_PRETTIFY), we should rename it to TOGGLE_WORD_WRAP.
