BUG#35795873: gr_cross_version_member_join fails on 8.0.36

gr_cross_version_member_join fails on 8.0.36 on the section:
```
 76 --echo
 77 --echo # 1.3. Make M2 patch version lower and make sure START GR fails.
 78
 79 SET @@GLOBAL.DEBUG= 'd,group_replication_compatibility_lower_patch_version';
 80
 81 --error ER_GROUP_REPLICATION_CONFIGURATION
 82 START GROUP_REPLICATION;
```
The server on the group (M1) is 8.0.36, the server joining (M2) is
8.0.35.
After the patch BUG#35397276: "Relax GR member join version
compatibility rules" that was pushed into 8.0.35, this is a valid
scenario, that is, both servers are 8.0.35 or higher 8.0 patch
version, thence considered compatible and M2 is allowed to join.

To fix the test failure, the test is updated to the new behavior, a
8.0.35 server can join a 8.0.36 group.
