[♻️ refactor] Investigate Caching of the `<Markdown>` component

[Fredkiss3]

What is the reason to do this refactor ?.

We want to cache the <Markdown> component because it can be very resource intensive.

Describe the work that needs to be done

Try different hypothesis, see Additional context below.

Additional context

Some leads :

• using unstable_cache to cache some steps of the component or the whole component : https://x.com/jamannnnnn/status/1729195304451477811?s=20
• Creating our own caching function that is injected into the global scope : https://x.com/tomlienard/status/1729186696552739090?s=20
• Serialize & DeSerialize the RSC stream : https://x.com/lubieowoce/status/1729229669109481710?s=20, https://codesandbox.io/p/devbox/rsc-in-rsc-forked-xr92mq?file=%2Fapp%2Fdeserialize.tsx%3A41%2C2
• [x] Are you willing to make a PR for this ?
