Correct dependency declaration

[maschino]

I want to:

• [ ] add a new rule
• [ ] edit an existing rule
• [x] improve the configuration :dizzy_face:

Explanation or benefit

Currently all of our dependencies are defined as peerDependencies. I think that we can easily switch the following packages to real dependencies:

• @typescript-eslint/eslint-plugin
• @typescript-eslint/parser
• eslint-plugin-react
• eslint-plugin-react-hooks

Maybe even use ~ instead of ^ as a version prefix to only allow patch releases for automatic upgrading. New minor versions could introduce new rules that we don't want.

I'm not sure about eslint itself tho - I think that it should be left as a peerDependency.

Examples of popular eslint configs and their dependencies:

• airbnb - mixed use of peer and normal dependencies
• canonical - eslint as peer, rest as dependency
• google - eslint as peer, no other dependencies
