Change the version of dependnecy 'go-swagger/go-swagger'

Is your feature request related to a problem? Please describe.

Currently argo-events depends on go-swagger/go-swagger@v0.31.0. But go-swagger may have retagged version v0.31.0, so the checksum from the code in github does not match the checksum saved in sum.golang.org.
So when trying to download go-swagger directly from Github, the following error will occur.

root@iZj6c5flh0q5ax3d1ttfuhZ:~/temp# GOPROXY=direct go get github.com/go-swagger/go-swagger@v0.31.0
go: downloading github.com/go-swagger/go-swagger v0.31.0
go: github.com/go-swagger/go-swagger@v0.31.0: verifying module: checksum mismatch

SECURITY ERROR
This download does NOT match the one reported by the checksum server.
The bits may have been replaced on the origin server, or an attacker may
have intercepted the download attempt.

For more information, see 'go help module-auth'.

Describe the solution you'd like
It seems that go-swagger haven't released a fix yet, so downgrade version might be the way to avoid this. AFAIK, dependabot automatic upgrades go-swagger from v0.30.4 to v0.31.0, so downgrade to v0.30.4 might be a good choice.
