Description

The subtitle prop in InlineNotification in Carbon 11 is now a string type. In Carbon 10, the prop is a node type. This creates React warning all over the places when we upgrade from Carbon 10 to 11. Can you change the subtitle prop back to a node type?

Steps to reproduce

Here is an example of my code snippet:

                    <InlineNotification
                      kind="error"
                      role="alert"
                      lowContrast
                      hideCloseButton
                      title={t('Failed to fetch')}
                      subtitle={
                        <>
                          {t(
                            'An error occurred when fetching secrets. Try again later.'
                          )}
                          {errorGuid && (
                            <span className="cpc--secret-input__error-guid">{` (${errorGuid})`}</span>
                          )}
                        </>
                      }
                    />
