[WIP][docs] Update components header to include product

[mnajdova]

IMPORTANT NOTE: This is a temporary fix, until the documentation for all products support the tabs API.

---

As we are removing the Unstyled suffix in the Base UI's components, we need to add support for namespace in the components header in the markdown files, as otherwise we will have conflicts in the components, for e.g. Tabs from @mui/material and Tabs from @mui/base.

This is needed in scenarios where Material UI components show the API of a Base UI's components in some of the components pages. I've also updated the generation of the links that point to Base UI's component to follow the new structure. To make this work, I needed to copy some utils from @mui-internal/api-docs-builder (I couldn't import the utils directly from here in the @mui/markdown as it is a commonjs module, while the api-docs-utils is an ES module).

I am closing the issue, we should rather remove the links from the Material UI's docs about the unstyled API, as we already have a section that this component is supported in the Base UI package.
