[Improvement]: Improve the CLI command outputs

[azinneera]

Description

Watched a video tutorial on YT and noticed some hiccups in the CLI user experience. IMO, the CLI help text can be more intuitive in guiding the user throughout the build process. For example, we can add a What's next as the last part of the command output. This has already been added for the bal build --cloud=docker. We should update the other commands also as follows:

Command	What’s Next
bal new <package-name> bal new <package-name> -t main	Execute bal run <package-name> to run the program Execute bal build <package-name> to build the executable JAR
bal new <package-name> -t service	Execute bal run <package-name> to run the service Execute bal build <package-name> to build the executable JAR
bal new <package-name> -t lib	Execute bal pack <package-name> to create the Ballerina archive
bal build	Execute java -jar <relative-path-to-the-executable-file> to run the program
bal pack	Execute bal push to publish the package to Ballerina Central.
