adding build for alma9

libcurl 7.53.1 would not compile properly on the alma9 development setup, producing the following error:

openldap.c:63:17: error: conflicting types for ‘ldap_connect’; have ‘CURLcode(struct connectdata *, _Bool *)’
   63 | static CURLcode ldap_connect(struct connectdata *conn, bool *done);
      |                 ^~~~~~~~~~~~
In file included from openldap.c:39:

      | ^~~~~~~~~~~~

I found on GitHub that this problem was solved in 7.77.0 (see https://github.com/curl/curl/issues/7004 ), so I went with libcurl 7.77.0.
