Adding envoPlastics subset

[raissameyer]

For our projects the UN Environment Working Group for SDG 14, I've created a subset for Plastics envoPlastics following the guidance on the corresponding wiki page, and @pbuttigieg's guidance here.

Please let me know if revisions are necessary.

Thanks @raissameyer - did you build the ontology locally to see if the Makefile generates the expected subsets?

[raissameyer]

No sorry, I have yet to do that. @pbuttigieg Would you mind linking me to some guidance on building the ontology locally?

We'll set up a call for this - but we should also take this opportunity to generate some documentation for the wiki

[raissameyer]

Thanks @pbuttigieg. I've now built ENVO locally, and the Makefile generated the expected subsets. including envoPlastics.

Following up on issue #1085 - it seems that it is not required to update SLIM list in Makefile, as the subsets were created despite them not being in that list. We should update the wiki page accordingly.

I've noted down my steps as I went along, and would be happy to clean that up for a wiki page (either to be added to the wiki on Making a new subset, or in a new one).

Many thanks for the revision and testing @raissameyer - merging!

[pbuttigieg]

Approved post hoc - @raissameyer this is a good PR to link to the documentation to show what code needs to be changed

Many thanks for the merge @pbuttigieg - I've updated ENVO's wiki page accordingly.
