Add entities for Bridge2AI Datasets

[caufieldjh]

Each of the Bridge2AI datasets should get their own entries in DataStandardOrTool (they aren't standards, but they are both examples of applying standards and sources of reference data). This will also facilitate linking to Use Cases.

Links:

• CM4AI: https://aimed.uab.edu/apex/r/tkg/cm4ai/
  • Cell maps are on NDEx
• Voice: https://healthdatanexus.ai/content/b2ai-voice/1.0/
• CHoRUS: TBA
• AI-READI: https://fairhub.io/datasets/2

• Versions should get their own entries. For example, the b2ai-voice data set needs its own entry, with another entry for v1.0.
• Each will need annotations for all of the applicable topics - in some cases this will be a long list!
• Assign a unique tag to denote these sets, like bridge2ai-data
