[PATCH] Correct error message when using -n and -o ignoreeof in interactive mode

[Milana]

Hi Bash Maintainers,

I recently encountered an issue while experimenting with different shell 
options in Bash. When launching Bash with both the `-n` (noexec) and `-o 
ignoreeof` flags in interactive mode (with no pipes or redirection), 
pressing `^D` (EOF) results in the message: "Use 'exit' to leave the 
shell."

Since no commands can be executed in this state due to the `noexec` 
option, this message might be misleading.

To address this, I've created a small patch that adjusts the error 
message depending on whether Bash is in command execution mode or not. 
This patch does not include translations of the new error message for 
other supported languages, as I wanted to avoid potential inaccuracies 
from machine translations.

Please find the patch attached. I am happy to make any further 
adjustments based on your feedback.

Thank you for your time and consideration.

Best regards,
Milana
