[LiveComponent][Bug] Header not recognize if chartset is added

[BeyerJC]

Hey !

We deploy our UI as a lambda on AWS and use API Gateway in front of. The APIG adds a charset to the content-type which afaik can not be disabled.

Instead of application/vnd.live-component+html the content-type returned is application/vnd.live-component+html; charset=UTF-8

I think the problem is here https://github.com/symfony/ux-live-component/blob/4c975aa9787c8ce1e2438dc53158abfa3623734f/assets/src/Component/index.ts#L299

Hey @WebMamba ! Thanks for the super fast reply and the PR 🎉

Its not easy to test because my local api gateway does not add the charset. I did some hacks and i think i was able to simulate it and can confirm that it works with your fix !
