Enable plugin:react/recommended ESLint rules

[ravicious]

The recommended set of lint rules includes many helpful rules such as react/jsx-key.

Just simply enabling the recommended rules causes ~260 errors to pop up. Majority of the violations are for:

• react/no-children-prop which is mostly stylistic and doesn't have autofix
• react/no-unescaped-entities which also at this point is mostly stylistic and doesn't have an autofix

Disabling those rules and running an autofix brings us to only about 20 violations which can be directly addressed:
