Current behavior 😯

As shown in this sandbox: https://codesandbox.io/s/mui-tabs-variant-issue-lk9v5c?file=/src/App.tsx

While I can add a new variant for Button and have it pass type checks via module augmentation, if I try the same thing for Tabs with:

declare module "@mui/material/Tabs" {
  interface TabsPropsVariantOverrides {
    outlined: true;
  }
}

both the theme declaration and component variant prop don't pass type checks.

Expected behavior 🤔

I should be able to add a custom variant to Tabs and have it pass TS type checks. I shouldn't have to @ts-ignore it.

Steps to reproduce 🕹

Steps:

1. Go to this sandbox: https://codesandbox.io/s/mui-tabs-variant-issue-lk9v5c?file=/src/App.tsx:1018-1055
2. Note variant displays an error

Context 🔦

I'm creating a new custom theme variant for tabs.

Your environment 🌎

@mui/material 5.9.3

typescript 4.5.5

Start with the linked CodeSandbox and reproduce the type errors for the Tabs variant and theme declaration using @mui/material 5.9.3 and TypeScript 4.5.5. Trace the Tabs component's TypeScript declarations and module-augmentation pattern, then verify that a custom variant passes type checks without @ts-ignore.
