runner.workspace is (now) an undocumented context property.

From the source file of Contexts docs,

{%- comment %}
The `runner.workspace` property is purposefully not documented. It is an early Actions property that now isn't relevant for users, compared to `github.workspace`. It is kept around for compatibility.

Maybe you can use github.workspace instead. Note runner.workspace and github.workspace are slightly different, see for example actions/runner#728.

We specifically have to use that because of the subtle difference. We use custom images in GA and this variable resolves to the correct folder.
