Adds a checkAllStrings option to the no-deprecated-colors rule.

If checkAllStrings is set to true, the no-deprecated-colors rule will check for deprecated colors in all strings. This is useful for catching uses of deprecated colors outside system props and the sx prop.

/* eslint primer-react/no-deprecated-colors: ["warn", {"checkAllStrings": true}] */
import {Box} from '@primer/components'
function ExampleComponent() {
 const styles = {
 // Enabling `checkAllStrings` will find deprecated colors used like this:
 color: 'text.primary'
 }
 return <Box sx={styles}>Hello</Box>
}

This option was needed to find all the uses of deprecated colors in Memex.
