Wrong function name in refresh token documentation

Describe the bug Documentation improvement

To Reproduce Steps to reproduce the behavior:

1. Go to ‘https://manfredsteyer.github.io/angular-oauth2-oidc/docs/additional-documentation/refreshing-a-token.html’

Expected behavior The function name refrenced in the documentation should match the name in the code

Additional context In the document the function name for refreshing a token seems to be wrong this.oauthService.refresh(); I think it should be: this.oauthService.refreshToken();
