Remove peer dependency requirements

[atwright147]

Hey,

This project has strict peer dep requirements set in the package.json, limiting React to a max of v17 and React-DnD v14 but it seems to work fine in React v18.2.0 with React-DnD v16.0.1. This suggests that the peer requirements are un-necessary.

Could they be removed please?

For anyone else wanting to use this with newer versions of React and React-DnD add the following to your package.json:

  "overrides": {
    "react-dnd-accessible-backend": {
      "react": "$react",
      "react-dnd": "$react-dnd"
    }
  }
