chore(react): add "wyw-in-js" field for tag processor

[layershifter]

Adds wyw-in-js field to package.json to support styles processing with WyW-in-JS compiler (https://wyw-in-js.dev/). The plan is to use this compiler for Vite/esbuild plugins (#41) and later switch our Webpack loader to it (#414).
