To Reproduce

1. enable noUncheckedIndexedAccess in tsconfig.json:

   {
       "compilerOptions": {
           "strict": true,
           "noUncheckedIndexedAccess": true,
           "skipLibCheck": false
       }
   }

2. run svelte-check

Expected behavior
no errors

after some investigating i noticed that this is caused by typesVersions in the @smui/common package incorrectly pointing to the source code. see #532
