Update version to 0.12.6 (pgcentralfoundation#1919)

Welcome to pgrx v0.12.6. This releases fixes a number of bugs, cleans up
various parts of the code, adds more Postgres `#include` headers, and
other little things.

To upgrade, first install cargo-pgrx with `cargo install cargo-pgrx
--version 0.12.6 --locked`. Then you can run `cargo pgrx upgrade` in
your extension's crate to update its dependencies.
