Description

GitHub supports the option to add code suggestions that can automatically overwrite the current code if committed. The user has the option to add infinitely many suggestions together in a batch before committing all in one single code review commit.
Any code review comment can contain suggestions by simply using

```suggestion``` (no text here, solely exists so that the quotes at the beginning will be displayed correctly)

The text that gets replaced is the text selected for this comment, resulting in this issue being effectively blocked until#12640 gets merged.
Of course, it would already be possible to implement, but limited to single-line code suggestions for now.

Later on, this feature could even be enhanced to use additional language highlighting, so that the recommendations would even be displayed in the style of the given language. This could look something like this then:

```<language> suggestion

, for example

```go suggestion

This is a useful feature as it allows integrating code suggestions way quicker and without the help of any external tool, where each change has to be manually located first.
