Use canonical Bioschemas prefix

[fbacall]

From reading a discussion here: BioSchemas/specifications#653 (comment)

It seems there was a conclusion to use https://bioschemas.org/terms/ as the prefix for Bioschemas' own types/properties.

The Bioschemas term mappings in the RO-Crate context should be updated:

"ComputationalWorkflow" : "https://bioschemas.org/terms/ComputationalWorkflow"
"input" : "https://bioschemas.org/terms/input"
"output" : "https://bioschemas.org/terms/output"
"FormalParameter" : "https://bioschemas.org/terms/FormalParameter"

CodeMeta are also establishing canonical URIs: codemeta/codemeta#468

Proposing for discussion with the steering committee: whether we should update these URIs now (in a minor/patch release) or wait for v2.0
