Describe the bug

While using DdRum.addError to send errors to Datadog, under some conditions the error message is replaced by the stack trace.

From empirical testing, I noticed that these conditions happen when the stack trace parameter starts with some words and a colon. Then the error message is replaced with what's after the colon in the stack trace.

Reproduction steps

From the errors below, the only ones that I can see the error message on Datadog are the 2nd and 4th messages.

// Error stack will start with "Error:", so message is replaced with stack trace
try {
  throw new Error("my test error 1");
} catch (e) {
  void DdRum.addError(
    "Error: my 1st message",
    ErrorSource.CUSTOM,
    (e as Error).stack ?? "empty stack",
    {
      a: 1,
    }
  );
}

// If a regular string is placed in the stack trace parameter, it works fine!
void DdRum.addError(
  "Error: my 2nd message",
  ErrorSource.CUSTOM,
  "my 2nd stack info",
  {
    a: 2,
  }
);    

// If stack trace param has a colon, error message is replaced! Not exclusive for Error objects
void DdRum.addError(
  "Error: my 3rd message",
  ErrorSource.CUSTOM,
  "Error: my 3rd stack info",
  {
    a: 3,
  }
);

// Works fine if I add a linebreak before the stack trace (my current workaround)
try {
  throw new Error("my test error 4");
} catch (e) {
  void DdRum.addError(
    "Error: my 4th message",
    ErrorSource.CUSTOM,
    "\n" + ((e as Error).stack ?? "empty stack"),
    {
      a: 4,
    }
  );
}

// Issue not exclusive to "Error:", any work preceding a colon will have the same effect
void DdRum.addError(
  "Error: my 5th message",
  ErrorSource.CUSTOM,
  "ABCD: my 5th stack info",
  {
    a: 5,
  }
);
