https://github.com/elastic/integrations/pull/17730 contains multiple comments for the PR Buildkite Detective

Instead of creating one new comment per buidlite detective, reuse the existing one if exists otherwise, create a new one.

This should avoid spamming with several comments but keep the UI usable.

For instance if you inspect https://github.com/elastic/integrations/pull/17730#issuecomment-4028861607 you will see that comment contains multiple editions, that's done with some other auotmation but illustrates what we are trying to achieve here
