Update version to 0.12.7

[eeeebbbbrrrr]

Welcome to pgrx v0.12.7. This is a minor release which adds a few more Postgres headers, fixes a possible crashing bug, adds some more smarts to #[pg_cast], and adds a new GucFlags variant.

To upgrade, please execute cargo install cargo-pgrx --version 0.12.7 --locked. Then you can run cargo pgrx upgrade against your extension crates.

The plan is that this will be the last release in the v0.12.x series.
