Warn about BIDS ID matching if dataset has imaging data

[alyssadai]

At the moment, if a user annotates a non-BIDS ID column in their phenotypic TSV as the participant ID, but then wants to include BIDS data in their JSONLD at the CLI step, they will need to go back and 1) add a new column with BIDS IDs to their TSVs and 2) re-annotate the TSV. This is pretty annoying, so we should instead have a clear warning during annotation that if a dataset has BIDS data that needs to be harmonized (or maybe if the user knows they intend to BIDSify data?), they should first generate and add BIDS IDs to the TSV before proceeding w/ the annotation.

We want to keep our issues up to date and active. This issue hasn't seen any activity in the last 75 days.
We have applied the _flag:stale label to indicate that this issue should be reviewed again.
When you review, please reread the spec and then apply one of these three options:

• prioritize: apply the flag:schedule label to suggest moving this issue into the backlog now
• close: if the issue is no longer relevant, explain why (give others a chance to reply) and then close.
• archive: sometimes an issue has important information or ideas but we won't work on it soon. In this case
  apply the someday label to show that this won't be prioritized. The stalebot will ignore issues with this
  label in the future. Use sparingly!

This is good to discuss further and implement as part of the validation.

Sounds good @rmanaem. To clarify, I think a simpler implementation that doesn't require input validation would be to always display a warning message (somewhere on the initial column annotation page?) that if the dataset also has BIDS imaging data that the user intends to harmonize with Neurobagel, the user should ensure that their uploaded tabular file contains matching subject IDs.
