Correct 'repository' references in bad rows schemas

[miike]

There's a spelling error in a few of the bad rows schemas - the error exists in the schemas themselves but the upstream components have the correct spelling.

I'm not sure this is the best way to correct - by overriding the schema or if it's better to just go with a new model version for each of the schemas, though this would then result in having to update both the upstream and downstream dependencies.

For downstream dependencies I don't think there's many but https://github.com/snowplow-incubator/snowplow-badrows will be one of them.

Oh, good catch, @miike.

So this part of JSON comes from Iglu Client https://github.com/snowplow/iglu-scala-client/blob/379c433048a9899fb55e8f9151f3c85b91cc927b/src/main/scala/com.snowplowanalytics.iglu/client/ClientError.scala#L53

It's also strange because in snowplow-badrows we have property-based testing checking that any generated BadRow is always valid against corresponding JSON schema. I need to investigate why we didn't catch this.
