The rename plugin relies on SYB to find located AST trees that need renaming. This breaks in GHC 9.2 because the representation of located AST trees has changed: it now includes exactprint annotations.
To make the rename plugin work in 9.2, we need to adjust the SYB queries to look for the new located AST types.
