self-hosted-runners: use Azure VM type with local storage

Let's switch to Standard_D8plds_v5. The "d" stands for:

d – Diskfull (local temp disk is present)

This means that we get an additional drive on the VM (D:\) that is
blaziingly fast. It leads to a ~25% speed increase when doing heavy
IO operations.
