CDK for Terraform 0.18 reduces synthesization time

The newest CDKTF release, version 0.18, significantly improves synthesization times for TypeScript, Python, and Java, enhancing the user experience by reducing processing time from several seconds to under a second. The release also includes various performance-related best practices, improved use of namespaces to reduce synth time, and faster code execution thanks to an upgraded JSII compiler. Additionally, CDKTF 0.18 introduces features such as auto-translation of Terraform HCL code to CDKTF-compatible languages using the `cdktf convert` command, improved multi-language provider documentation, and plans for future releases that include basic support for config-driven import and better refactoring capabilities.
