[FIX] website: hide link popover on social share

To reproduce the issue:

- Website > Edit mode > Add "Share" block.
- Cannot edit the link by clicking a social share item ("Edit link"
on link popover doesn't work).

Since 15.x, "Share" snippet items are not meant to be user links but
buttons to share the page on the related social media. It is also
useless to update those links after the update on [1], since they will
be replaced by the right values "on social item click" (the shared URL
may be updated during the page use as on product pages).

The goal of this commit is to fix this behavior and prevent the link
popover from appearing on items (by setting the `o_no_link_popover`
class right after the snippet is dropped into a drop zone).
