Title: exec command in Nushell: Execute external commands

Summary

The `exec` command in Nushell executes an external command. On Unix-based systems, it replaces the current process with the command. On Windows, Nushell waits for the command to finish and then exits with the command's exit code. The command takes a variable number of arguments that are passed to the external command.
