Add simple way to remove individual field items

In the case of Oscar widget, requires deleting both times and start date.

Relevant 📌 Allow for deletion of a single value of a multiple value field Fixed

To have access to a deleted button per date slot, I propose the following solution:

- Update the drupal core to the last version (8.9.7)
- Install the patch of comment 214 of issue 1038316 :
* https://www.drupal.org/project/drupal/issues/1038316 📌 Allow for deletion of a single value of a multiple value field Fixed
* https://www.drupal.org/files/issues/2020-06-11/1038316-214.patch →
- Then install the patch I just posted (compatible with 2.0.0-rc1 version)

You will then get a delete button for each date slot.

Change issue status

The same patch with css style

we can either postpone this issue and block on the core issue, or develop a self contained solution here. The core issue isn’t progressing, so leaving this as active in case someone wants to develop a new patch with all the things required. Note: I’m not suggesting copying the majority of the core patch, rather something a lot slimmer.

📌 Allow for deletion of a single value of a multiple value field Fixed has been committed.

It seems like there is nothing to be done here as it works out of the box with HEAD.

Accidentally edited the issue summary instead of embedding these in the last comment.

Closing outdated, we can open follow up issues if there are bugs.
