Re: [sdw] ssn:ext proposal comment: Note on 4.2.4 (#1153)

See updated text at https://raw.githack.com/w3c/sdw/simon-ssn-ext/proposals/ssn-extensions/index.html#has-sampled-feature

Note that `sosa:hasUltimateFeatureOfInterest` links from an **activity** (Observation, Sampling, Actuation) - the purple boxes in [Figure 3](https://w3c.github.io/sdw/proposals/ssn-extensions/#fig-sample-chain-geology) - to a FOI. 
And `sosa:hasSampledFeature` links from a Sample (**entity** in Prov-speak) to its original predecessor, typically via a chain of `sosa:isSampleOf` edges. 
`sosa:hasOriginalSample`, links from a Sample (**entity** in Prov-speak) to a key predecessor, alsovia a chain of `sosa:isSampleOf` edges. but not necessarily all the way to the end if you don't want it to - see the diagram [Figure 3](https://w3c.github.io/sdw/proposals/ssn-extensions/#fig-sample-chain-geology).
