Debounce webhooks with Retry-After header (docs?)

### Is your proposal related to a problem?

Hi folks, the docs indicate that "The Retry-After header can be used for retrying/rate-limiting/debouncing your webhook triggers.". I'm curious how debouncing a webhook could work?

My use-case is I trigger a computation when a column changes, but that column can change very often and I'd like to limit how often the webhook would be called. I've asked for this [on Discord](https://discord.com/channels/407792526867693568/428469959530643466/1017639961459167272) and was asked to post it here.

### Describe the solution you'd like

If i set the Retry-After header to let say 5m, will all other triggers within that 5m time window be ignored? This needs further description in the docs I believe. I'm open to adding that in if I can understand it :). Also do you have a recommended way to manage the same webhook being called multiple times and how to determine whether to process or debounce the event?

### Describe alternatives you've considered

N.A.

### If the feature is approved, would you be willing to submit a PR?

I'm ok to open a documentation PR.
