Run actions/setup-go after checking out complement

[DMRobertson]

This should suppress the warnings in test runs, e.g. from https://github.com/matrix-org/synapse/actions/runs/6673818366?pr=16565

and presumably make it mildly quicker to prepare the complement test binary.

Let's see if this works by checking https://github.com/matrix-org/synapse/actions/runs/6678497686?pr=16567

Still has a warning about go version but unsure we care?

Sounds like an oversight in the complement CI too then?

More like in complement's dependency/project definitions, but otherwise yes. matrix-org/complement#687 should fix.

complement change landed. Rerunning.

Complement seems happier now.
