[FIX] website_event: social icons alignment fix

A revamp of the scss of 's_share' in '14.0' has caused an issue with the
class '.o_wevent_social_link' of 'website_event', making a wrong
alignment of the social media icons used in this module, especially in
'event_templates_page_registration'.

For this reason, this commit fixes this issue by setting the display of
the '.o_wevent_social_link' class as an 'inline-flex', vertically and
horizontally centered.
