Facebook import: link field is deprecated for versions v3.3 and higher

[Former user]

I am using version 1.4.1 on TYPO3 8.7.12. When importing from facebook I get this error in the log: pb_social - flexform 422 on page 90 tab facebook: 1559547942 (#12) link field is deprecated for versions v3.3 and higher (msg#4.0.32767)

On the page the extension does not show any posts. Any ideas?

I figured out that this can be fixed by replacing link with user_link in FacebookAdapter.php, however that returns empty links.
At least $options->settings['facebookLinktopost'] still works and the fix makes the import run again. An official fix would be great.

These changes ignore the default Graph API version as described here: https://developers.facebook.com/blog/post/2018/05/01/facebook-login-updates-further-protect-privacy/
