Add conformsTo to identify profile conformance

[stain]

Following https://www.researchobject.org/ro-crate/1.2-DRAFT/profiles but with "conformsTo" applied to "./" as suggested in ResearchObject/ro-crate#153 (comment) rather than conformsTo

Example for provenance crate.

Process Crate:

• https://w3id.org/ro/wfrun/process/0.1

Workflow Crate:

• https://w3id.org/ro/wfrun/process/0.1
• https://w3id.org/ro/wfrun/workflow/0.1
• https://w3id.org/workflowhub/workflow-ro-crate/1.0

Provenance Crate:

• https://w3id.org/ro/wfrun/process/0.1
• https://w3id.org/ro/wfrun/workflow/0.1
• https://w3id.org/ro/wfrun/provenance/0.1
• https://w3id.org/workflowhub/workflow-ro-crate/1.0

Notes:

• These PIDs won't work before 0.1 versions of the profiles are released, e.g. https://w3id.org/ro/wfrun/process/0.1 redirects to https://www.researchobject.org/workflow-run-crate/profiles/0.1/process_run_crate which is currently at https://www.researchobject.org/workflow-run-crate/profiles/0.1-DRAFT/process_run_crate etc.
• https://www.researchobject.org/ro-crate/1.2-DRAFT/profiles does not have the concept of inheritence, perhaps deliberately so that clients can assume profile conformance of the bases even if it has no knowledge of the other profiles (inheritence would also require retrieval of machine-readable Crate profiles)
• conformsTo always goes to a profile PID with major.minor version
• https://about.workflowhub.eu/Workflow-RO-Crate/#metadata-file-descriptor assumes RO-Crate 1.1 (which said nothing about profiles), and applies conformsTo to ro-crate-metadata.json. To keep conformance with that one (before it can be updated to 1.2 once that is released) I have kept that in the examples here, but also added the Workflow RO-Crate PID to make it consistent with 1.2
• It is not sufficient with just wfrun/process and workflowhub/workflow-ro-crate as wfrun/workflow adds a requirement for the CreateAction to be connected to the mainEntity workflow
• wfrun/provenance is again different from wfrun/workflow, e.g. it adds OrganizeAction and ControlAction

Agreed that relying on inheritance would be quite tricky. Much easier for consumers to check conformance if all profiles are explicitly listed as shown here.

Yeah, I think we can still indicate that inheritance in the Profile Crate for documentation, but that it should keep it explicit in conformsTo in each conforming Crate - just like we have those lovely @type arrays rather than some ontology with inferred subclasses. Will add that to the RO-Crate 1.2 page.
