[DX] Rename error prefix to use open-source project name?

[oliviertassinari]

What's the problem? 🤔

Most of the codebase (MUI X included) throws errors with this convention: throw new MuiError('MUI: . This feels strange. Even if we make MUI the UI library, that has a Joy Design theme, and a Material Design theme, it still feels strange to have an error about Base UI or MUI X prefixed with MUI.

So my proposal would be to replace these prefixes to be more specific. The side benefit is that it will train developers to learn about these different projects.

I was inspired to open this issue from mui/mui-x#10611, which was opened on the wrong repository.
