Use new column names for biomarkers

[bherr2]

Biomarker columns will now be named according to the mapping below.

• In the ASCT+B API support the old naming Bx, but also support the new mapping as below. This should be a server only change.
• Update data format markdown docs to reflect this.

Mapping:

• Proteoform → BProteoform (NEW)
• Lipid —> BLipid (NEW)
• Metabolite —> BMetabolite (NEW)
• Protein —> BProtein (Renamed from OLD BP)
• Gene —>BGene (Renamed from OLD BG)

This should be as easy as adding new mappings to: https://github.com/hubmapconsortium/ccf-asct-reporter/blob/main/asctb-api/src/index.ts#L69-L78
