offlineExchange import from @urql/exchange-graphcache not respecting `useTypeImports`

### Which packages are impacted by your issue?

@graphql-codegen/typescript-urql-graphcache

### Describe the bug

The code generator adds an import for `offlineExchange` from '@urql/exchange-graphcache', but it is not using the `config.useTypeImports` config to determine if the import should by type import.

`offlineExchange` is only used in the following generated code (which only requires types):

```
export type GraphCacheConfig = Parameters[0] & {
updates?: GraphCacheUpdaters,
keys?: GraphCacheKeysConfig,
optimistic?: GraphCacheOptimisticUpdaters,
resolvers?: GraphCacheResolvers,
};
```

Using the library with `importsNotUsedAsValues` set to `error` will throw an error with the imported code.
