Updating the table editable values

As I consider your use case more, if your end goal is to use the selections so users can get each repository's releases you should be fine with the list view. If you need to have an overall "get all the selections at once" process flow then you may need to use a different approach to get all of the user inputs collected (maybe a form entry submission page or modal?)

Here is an example of the list view reporting the selected dropdown values that shouldn't be hard to extrapolate from. The List View is using the data source's primary key as its own and then the select components are tied to the "item" where the click is happening:

As a POC it should help to get you started on using List View component data on an item by item basis.
