Related values always includes a link display on o2m

[Dominic-Marcelino]

Describe the Improvement

On o2m fields, when selecting "related values" as display, it will always display a link to the item.

In contrast to the interface, the display config doesn't allows us to hide the link. This leads to an inconsistency, as the display will always show a link to the items page, even if we wan't to hide the direct items access.

It seems like the display uses the list-o2m.vue interface under the hood, which has a prop to control this behaviour:

directus/app/src/interfaces/list-o2m/list-o2m.vue

Line 40 in ebd0c06

enableLink?: boolean;

I'd suggest to add a new config to the display config, which allows to disable the link (same as in the interface)
