Review comment (suggestion):
```suggestion
func (s *EnterpriseService) UpdateAppInstallationRepositories(ctx context.Context, enterprise, org string, installationID int64, opts UpdateAppInstallationRepositoriesOptions) (*Installation, *Response, error) {
```
The options should be required for this endpoint, as discussed in [comment](https://github.com/google/go-github/pull/3831#discussion_r2533822180)

Code after:
	u, err := addOptions(u, opts)
	if err != nil {
		return nil, nil, err
	}

	req, err := s.client.NewRequest("GET", u, nil)
	if err != nil {

	var r []*AccessibleRepository
	resp, err := s.client.Do(ctx, req, &r)
	if err != nil {
		return nil, resp, err
	}
