fix analytics message

[ghost]

"klothoupdate is available" -> "klotho update is available"

Standard checks

• Unit tests: n/a
• Docs: not needed
• Backwards compatibility: will break analytics aggregation if searching for "klothoupdate", but @AlaShibanAtKlo requested it, so I think he's fine with that
