Add missing @babel/plugin-proposal-class-properties dev dependency

[Kocal]

I was not able to run tests after cloning the repository and installing dependencies, because @babel/plugin-proposal-class-properties is missing:

➜  symfony-stimulus-bridge git:(main) yarn test
! The local project doesn't define a 'packageManager' field. Corepack will now add one referencing [email protected]+sha512.a6b2f7906b721bba3d67d4aff083df04dad64c399707841b7acf00f6b133b7ac24255f2652fa22ae3534329dc6180534e98d17432037ff6fd140556e2bb3137e.

    - Did you mean "@babel/plugin-transform-class-properties"?

    Make sure that all the Babel plugins and presets you are using
    are defined as dependencies or devDependencies in your package.json
    file. It's possible that the missing plugin is loaded by a preset
    you are using that forgot to add the plugin to its dependencies: you
    can workaround this problem by explicitly adding the missing package
    to your top-level package.json.
