Feature: Clarify that docs issues typically don't get version labels

Describe the enhancement or feature you would like

In learning how to label / triage came across a docs issue where I got the labels fairly off and I would like to add more details to the devguide to help future triagers get it right the first time. In particular:

1. docs issues don't typically get version labels (Those tend to only go with code changes)
2. If there's no code change needed then stdlib, extension-modules, etc. tend not to apply.

Describe alternatives you have considered

Additional context

该 issue 没有指出 devguide 中的文件或章节；首先定位有关标记和 triage 的文档。添加说明，指出 docs issue 通常不会添加版本标签或代码区域标签（例如 stdlib 和 extension-modules），然后确认措辞与周围的指导内容相符。
