test: fix NUTs @W-22293348@

What does this PR do?

In this PR 398 we introduced a change that broke some NUTs. When the original PR was merged, these legitimate failures were masked by a server issues that made all test to failed. Now that the environment is stable, I've identified and resolved the underlying issues in the test suite.

The original change removed try/catch block that was unnecessarily altering error message handling. By removing this, the error output now aligns with error handling used across other commands.

What issues does this PR fix or reference?

lGTM, could we add an error codes section to publish, like

  public static readonly errorCodes = toHelpSection('ERROR CODES', {
    'Succeeded (0)': 'Agent published successfully without errors.',
    'Failed (1)': 'Compilation errors found in the Agent Script file.',
  });
