[IMP] project: hide the 'share' action in the list view of the project

Current behavior before PR:
When sharing multiple projects in list view, only one project gets shared,
which creates issues, misguides, and causes confusion.

After this PR:
to get rid of those issues, we hided the 'share' action in the list
view of the project.
and also removed it from the form view too as it is redundant with the
share buttons
