Update composer.json and Evergreen matrices for 1.15.0 (#1006)

* Bump PHPC versions in Evergreen matrix

* Bump latest-stable server version to MongoDB 6.0

* Bump extension requirement and branch alias in composer.json

The 1.14.x series is being skipped to restore version parity between the extension and library.
