feat(deps): react and react-dom peer dependencies

[RubenSibon]

Describe the pull request

Thank you for contributing to the project!
Please use this template to help us handle your PR smoothly.

What

Increments the peer dependencies for react and react-dom so that the React package supports React 17, 18 and 19.

Why

React 19 has come out recently and React 16 is no longer used much.

How

Changing numbers in the package.json of the react package.

The ADS has been tested with:

• Next.js with React 19.x
• React Router 7 with React 19.x
• Remix 2 with React 19.x (manual upgrade) (pages have partially been implemented; expect broken links)

You can run above linked projects locally to check it our for yourself.

Additional notes

• Do we want to upgrade ADS own React dependencies to 19.x?

[alimpens]

Removing 16 is a breaking change, we shouldn't do that if it isn't necessary.

[RubenSibon]

Alright, that would be okay with me.

But have you seen this DES-1130 comment?

There are, presumably, only 3 projects within the Amsterdam GitHub that use React 16. Of those 3, 2 belong to OpenStad. I checked with Ian Rieken, who maintains the OpenStad-stack, and he says those two repo's don't use the ADS anyway and are no longer maintained. Whether makkelijkemarkt-kiesjekraam uses the ADS I do not know.

There could be projects that were not counted or are outside of the Amsterdam GitHub organisation that use the ADS.

I think this is a feat, it definitely belongs in the changelog. And if we decide to not support React 16 anymore, it's a breaking feature.
