added gcloud intro

- Created a new script `instalL_asciinema.sh` to automate the installation of asciinema.
- The script detects the operating system and architecture to download the appropriate binary.
- Supports Linux (both musl and GNU) and macOS (Darwin).
- Sets executable permissions for the downloaded binary and verifies the installation by displaying the version.
