[MEL]: Fix size of share links

[cmoinier]

Description

This PR adds an extraClass to the gn-ui-data-view-share component, which has no impact on the display of the component in gn-ui, but will allow the webcomponent on MEL to be stretched all the way across the preview square (see https://mel.integration.apps.gs-fr-prod.camptocamp.com/catalogue/dataset/ville-roubaix::activit%C3%A9-sportive-sport-pass-roubaix).
Removing the container-lg and lg:mx-auto for the MEL fixes that.

Thanks @cmoinier, good find! The change makes sense to me :-)

I think this change makes sense as a component such as gn-ui-data-view-share should not have this kind of layout responsibility. Thanks! Just made a suggestion regarding where to put those layout classes
