chore: Install Couchbase PHP extension in CI workflow

This commit adds steps to the continuous integration workflow to install and enable the Couchbase PHP extension. The extension is installed using the `pecl install` command, and then enabled by appending the `extension=couchbase.so` line to the PHP configuration file. This ensures that the necessary extension is available for the project's functionality.

Closes #123
