Update bin/check-examples.sh to v3.0.1

[bact]

bin/check-examples.sh uses https://spdx.org/rdf/3.0.0/spdx-model.ttl.

Needs to update to 3.0.1 one, once it is ready.

Hi @bact @kestewart , I was thinking if this repo is open to contributions from other members also, like me, and if yes, I would really like to start contributing to the project. Can you tell me what public channels do we use to connect apart from mail groups if there is something.
