Add explicit scheme so the share extension is part of the build

Without an explicit scheme, xcodebuild's auto-scheme only reports the
app target's settings — which made the Mac mini builder skip the share
extension when generating provisioning profiles, causing the export to
fail with "GiteaIssueShare.appex requires a provisioning profile."
