[Feat]: Add react v19 to peer deps

[Yonom]

Thanks a lot for this package

I get the following warning from pnpm after upgrading to NextJS v15 (released today), which installs react 19 RC

React 19 is technically still in RC stage, but since a stable version of a major Metaframework is installing it, it's a sign that it's ready for production use and will now be used by many projects.

└─┬ embla-carousel-react 8.3.0
  └── ✕ unmet peer react@"^16.8.0 || ^17.0.1 || ^18.0.0": found 19.0.0-rc-65a56d0e-20241020

Thank you for your contribution @Yonom, much appreciated 👍.

I have one question

I haven't checked out React 19 so I don't know if it has any breaking changes that will affect/break the useEmblaCarousel hook. Will it be compatible without any changes?

[Yonom]

I couldn't spot any issues in my installation of it!

By looking at the official upgrade guide, the only thing that seems to "apply" to this codebase is the useRef part, which already is implemented this way on useEmblaCarousel hook.

@ricardo-a-alves-alb do you mean that the useRef code in useEmblaCarousel will work with React 19 as is or that it needs to change?

As-is, it should work properly. The difference from 18 to 19 is that useRef() does not allow no arguments passed. Since useEmblaCarousel always passes a default value to useRef(), it should work with no issues.

@ricardo-a-alves-alb thanks for digging into this. I will merge this soon. @Yonom could you check if this PR needs to be rebased and do that on the latest master in case it’s necessary?

[davidjerleke]

Thanks @Yonom for your contribution and @ricardo-a-alves-alb for the reference 👍.

@Yonom and @ricardo-a-alves-alb I just released this in v8.3.1.

Nice! One more dependency updated so I can upgrade to Next.js 15 later on 😄
