Update version to 0.16.0

[eeeebbbbrrrr]

Welcome to pgrx v0.16.0.

This release contains support for Postgres 18beta2 and has some breaking changes in that support for pgrx' "hooks" implementation, which has been deprecated for over a year, has finally been removed.

Additionally, due to unsoundness issues, direct support for using heapless in shared memory has been removed. Users can still do this themselves, which requires them to assert they're taking responsibility of possible unsoundness issues.

As always, first install the latest cargo-pgrx with:

$ cargo install cargo-pgrx --version 0.16.0 --locked

Then you're free to run cargo pgrx upgrade in the root of all your extension crates.

To pickup pg18beta2 support you'll also want to run cargo pgrx init so that it can be downloaded and compiled.
