refactor(token-bottom-sheet): remove unused generic (#5484)

### Description

This was added in #4242 when we
were working towards multichain, but now there shouldn't be a need for
multiple TokenBalance types

### Test plan

CI

### Related issues

N/A

### Backwards compatibility

Yes

### Network scalability

If a new NetworkId and/or Network are added in the future, the changes
in this PR will:

- [x] Continue to work without code changes, OR trigger a compilation
error (guaranteeing we find it when a new network is added)
