docs: kernel: Clarify printk_ratelimit_burst reset behavior
Add clarification that the printk_ratelimit_burst window resets after
printk_ratelimit seconds have elapsed, allowing another burst of
messages to be sent. This helps users understand that the rate limiting
is not permanent but operates in periodic windows.
