fix(llm): add trailing slash to customOpenAiHost && fixed #77

Add a trailing slash to the `customOpenAiHost` if it doesn't already have one. This ensures that the URL is properly formatted.

Also update the corresponding message in the AutoDevBundle.properties file to indicate that the `customOpenAIHost` parameter must end with a slash.
