chore: Fix windows test tags (#5953)

After #5909 we prepend `gore2regex`
tag if it's missing. In go you need to stick to the same separator for
tags e.g. spaces _or_ commas. In all places we use space as separator
except for windows test. So windows test breaks because we end up with
`-tags "gore2regex nodocker,nonetwork"`.
