Subject: [PATCH] Update Percentage.tsx

useTheme() on line 32 returns null so I tested this change to the import on my local copy, which gets the sonar plugin working. Other plugins seem to be importing from '@material-ui/core', e.g. https://github.com/backstage/backstage/blob/7ee15d2c5b40a8984aacabe7bdf5ccab759d95a6/plugins/catalog/src/components/CatalogFilter/AllServicesCount.tsx#L19
