List of NCBI isoforms in data json

[tanyasg]

Some cell lines have multiple isoforms that are displayed in the gene editing tab:

These are separate entries in the data/cell_line_catalog.json but should be implemented as a list instead

Acceptance criteria:
NCBI isoforms should be stored in the following format in the json:

Format should work for single gene edit lines and multi-gene edit lines; each gene can have 1 or more isoforms

[tanyasg]

NCBI list should also accommodate multi-edit lines. Currently dual edits end up having an extra "NCBI isoforms" line that should not be there.
There is also an extra slash after the gene symbols (only seeing this for dual edit lines)

What would be the impact of this change? How much work would it be? Would there be any front end changes? Should we maintain this ticket?
