Fix distances and style for user profile in Blogs. Right now the user name and publication date in blog entry header is displayed with a font size of 16px when it should be 14px. (This is probably due to the change of body font-size from 0.875rem to 1rem).
- Change user name and publication font size with 14px
- The distance between user sticker and publication date should be 16px
- Change color for the publication date should be displayed in #6B6C7E
Notice this bug is just for the profile component added in the list view of Blogs.
