Callmap.php should be updated too

All of the ldap functions in callmap.php seem to use the old resource type. How does this work with different php versions?

Please take a look at https://psalm.dev/docs/contributing/editing_callmaps/ for the full explanation. Short version: callmap.php contains current signature and versionned files alters it for each successive older version to match with the user's version

Updated ldap_unbind in callmap. It looks like there are other incorrect types for ldap functions. I can try to open another PR for that later, but it's a lot of manual checking.

Thanks! Follow up is welcome :)

Some contributor recently made a tool to detect inconsistencies in callmaps (through reflection) and flagged ldap_ functions as potentially wrong: https://github.com/vimeo/psalm/pull/8104/files#diff-b16377a21d55a13a48cbdbdfbdf7479b2d9dda80f93b3b81202f88bd1e230b13R97
Your fix was probably the reason that justified excluding this range of functions

You could try to remove this line in a new PR an look at CI results for failures in order to identify cases that would need fixing
