Heatmap color as annotation background color.

[Jun10ng]

I think it is very intuitive to use the heatmap color as the annotation background color. Especially for users who migrated from Jetbrain IDE. I found that there were similar issue in the past. #1637 Although the conversation indicated that it was supported, I did not find the relevant feature.

Now, I have two questions

1. Is this feature supported now?

2. I've implemented it on my local repo, and I plan to submit a PR, but I thinks it would be better that using a new configuration item to control this feature. Do you have any suggestions? Such as gitlens.fileAnnotations.HeatmapAsBacgroundColor

The below screenshot is my implement demo on my local repo:
