## What
remove unused .eslintignore in medusa-react package
## Why
Some IDEs, like JetBrains, will establish the eslint working directory by finding the nearest .eslintrc or .eslintignore file. The .eslintignore in `/packages/medusa-react` adds complexity to configuring and resolving eslint for that package.
## How
.eslintignore is already declared at the root of the monorepo and /packages/medusa-react is already ignored as a whole. We can safely remove the `.eslintignore` from `/packages/medusa-react`
