[useMediaQuery] Remove unstable prefix

[alirni]

The "useTheme" was mistakenly imported

Breaking changes

-import { unstable_useMediaQuery as useMediaQuery } from '@material-ui/core/useMediaQuery';
+import useMediaQuery from '@material-ui/core/useMediaQuery';

This hook is not part of @material-ui/core but @material-ui/styles. Why do you think this import is wrong?

[oliviertassinari]

@alirni The suggested change is wrong as we are speaking. The only useTheme() hook we have comes from @material-ui/style.

Now, I think that there is an important flaw here, this module doesn't have any default theme. I'm working on re-exporting #14560 the @material-ui/style modules in @material-ui/core/style with the default Material-UI theme. We should be able to merge your pull request once the effort is completed.

@oliviertassinari
In my project, useTheme() does not exist in this path @material-ui/style.
Maybe you made a mistake in the @material-ui/style output. However, using the useTheme() with this path @material-ui/core/style is not a problem.
