Improve Error Message for Invalid API Key

[leonid20000]

Issue Description:

Currently, when an invalid API key is provided in odin-slides, the error message displayed is not very informative. The message "Hmm, not sure what you want so I did not make any changes. Try differently: >" does not clearly indicate that the API key is invalid, potentially leading users to overlook this issue.

This issue was discovered while resolving Issue #3

Suggested Solution:

To enhance the user experience and facilitate troubleshooting, it is recommended to improve the error message for invalid API keys. The enhanced error message should explicitly state that the provided API key is invalid and prompt the user to check and update it.

Expected Behavior:

When an invalid API key is detected, odin-slides should display an error message similar to the following:

"Error: Invalid API key. Please check and update your API key."

This informative error message will help users quickly identify and resolve issues related to invalid API keys, ensuring a smoother user experience.

Implementing an improved error message for invalid API keys will significantly enhance the usability of the odin-slides.
