[RN72][skip-ci] Rename eslint NPM script to eslint:all

Summary:
By overloading the eslint name, we make it impossible to run eslint from the root on a specific file.

To avoid that issue, this diff renames the eslint script name to eslint:all. Now invocations of yarn eslint will go straight to the package binary, which allows us to run it on a specific file, eg.:

yarn eslint --fix native/chat/swipeable-message.react.js

Depends on D10540

Test Plan: Try yarn eslint --fix native/chat/swipeable-message.react.js
