Align experimental feature disclaimers in docs

[Savio-Sou]

Problem

We currently have different versions of experimental feature disclaimers in our docs:

• https://noir-lang.org/docs/dev/noir/concepts/oracles/
• https://noir-lang.org/docs/dev/noir/standard_library/containers/vec/
• https://noir-lang.org/docs/dev/noir/concepts/data_bus/
• https://noir-lang.org/docs/dev/noir/concepts/data_types/slices/

Happy case

We should create one disclaimer module, then update the pages to link to it instead.

The disclaimer should specify:

• The feature is experimental
• Documentation of the feature is incomplete and could be out of date
• Documentation contributions are welcome: https://github.com/noir-lang/noir

🫡 Docusaurus's docs if it helps: https://docusaurus.io/docs/

PR welcome!

Yes, I even know how to use Docusaurus, so there won't be a problem with that.
What you want me to do is remove where their are two disclaimer modules, right?

[Savio-Sou]

There are currently admonitions on different pages in the docs that serve the same purpose: informing readers that the language feature is experimental.

For example:

It would be good to create a module for such an admonition, then simply link to it on the doc pages necessary (instead of each page having its own different admonition).

Supplemented additional context in the Issue body.

like a reusable component that will be imported in the doc page
