Use official ghcr.io/tideways/php docker image for Tideways installation

The provided tooling will do the heavy lifting of choosing the correct `.so`
file for a given PHP version, it will automatically support other architectures
and downloading and verification is handled by Docker instead of a manual
`curl` command.
