fix(homepage): remove duplicate repo events

temporary solution to users who accidentally ran `ngit claim` on a repo
they didn't own

ngit will select the version listed in `maintainers.yaml` if present but
git together doesn't have a trusted copy of the underlying repo to find
the correct `maintainers.yaml`

presenting multiple options for the user combined with a staring /
following system linked with WoT is the long term plan
