Outreachy Presentations for the May 2022 Round

The OCaml community participated in the May 2022 round of [Outreachy](https://www.outreachy.org/) internships. Two interns worked on a range of projects including Multicore OCaml benchmarks and TopoJSON parsing libraries. This meeting was an opportunity for the interns to present their work and for the community to ask questions and was [originally announced on the discuss forum](https://discuss.ocaml.org/t/outreachy-summer-22-closing-commemoration-session-on-23rd-sept/10450).
