[stylelint-polaris] Add postcss-scss and stylelint-scss as dependencies (#11658)

### WHY are these changes introduced?

Currently, consumers of `stylelint-polaris`, which leverages
`postcss-scss` and `stylelint-scss` internally, are required to install
these packages as `devDependencies`. This is the case even if they are
not directly utilized within their applications. A more streamlined
approach would be to incorporate these packages directly within the
`stylelint-polaris` package as dependencies. This adjustment would
enable consumers to eliminate these packages from their
`devDependencies`, thereby simplifying their dependency management and
making the dependencies more transparent.
