Title: Add Go language support

Description:

This pull request adds support for the Go programming language to our project. The implementation includes test cases for basic functionality and standard input/output operations.

Changes made:

• Added Go language execution support in the main execution engine
• Implemented "Hello World" test case for Go
• Implemented standard input processing test case for Go
• Updated relevant configuration files to include Go

New test cases:

1. "go : hello world" - Tests basic Go program execution
2. "go : print stdin" - Tests Go's ability to read from standard input and output

These test cases follow the existing structure and format of other language test cases in the project.

Testing:

• All new test cases pass successfully
• Existing test cases for other languages remain unaffected

Dependencies:

• This feature requires Go to be installed on the system running the project

Please review and let me know if any changes or additional information is needed.
