### Describe the bug

When using `import-types` with `typescript-urql`, the generated document variable will also incorrectly get prefixed. This same behavior also occurs if you set the `importOperationTypesFrom` config manually with no presets.

```typescript
import * as Types from './graphql.d'

const UserDocument = ...

export function useUserQuery(options?: Omit, 'query'>) {
return Urql.useQuery({ query: Types.UserDocument, ...options });
};
```

I believe the problem code is here:

https://github.com/dotansimha/graphql-code-generator/blob/cb59afdcea134385e34d544b90e1cd189945230a/packages/plugins/typescript/urql/src/visitor.ts#L145-L147

**Sidenote**

This greedy prefixing behavior does not occur if you use the `near-operation-file` preset with `baseTypesPath`+`importTypesNamespace`. It actually does the opposite and doesn't prefix anything; you need to use the `typesPrefix` config. But at least that config does not prefix the document variable.

### To Reproduce

My `codegen.yml` config file:

```yml
schema: schema.graphql
documents: document.graphql
generates:
graphql.d.ts:
plugins:
- typescript
- typescript-operations
index.ts:
preset: "import-types"
presetConfig:
typesPath: "./graphql.d"
plugins:
- typescript-urql
```

### Expected behavior

A `Types.` prefix will not be added to the document variable when using `import-types`

### Workaround

Use the `add` plugin with `typesPrefix` config instead of `import-types` preset.

```yml
schema: schema.graphql
documents: document.graphql
generates:
graphql.d.ts:
plugins:
- typescript
- typescript-operations
index.ts:
# preset: "import-types"
# presetConfig:
# typesPath: "./graphql.d"
plugins:
- typescript-urql
- add:
content: "import * as Types from './graphql.d'"
config:
typesPrefix: "Types."
```
