[danicahelb]

user datasets Share dataset and Remove button updates needed for mbio and clinepi

My studies table:

• [x] change verbiage on button from Share datasets to Grant Access to Studies
• [x] Grant Access to Studies button should be teal and icon should be on the left
• [x] Change verbiage on button from Remove to Delete
• [x] Delete button should stay gray but icon should be on the left

My study status page:

• [x] change verbiage on button from Share to Grant Access to Study
• [x] Grant Access to Study button should be teal and icon should be on the left
• [x] Delete button should stay gray but icon should be on the left
• [x] Swap positions of buttons: Grant Access to Study button should be on the left and Delete button should be on the right
