change the style of the publications section of the landing page

[kmexter]

For the publications part of the landing page, the style needs some tweaking. Change it to

• a left-side aligned bulleted list that will each have the text like this: Smith, J., Smith, P., Smith, K., 2020, "some lovely article title that will probaby be quite long as they always are", Biology Journal 24, p345. This paper is about something very interesting that we worked on very hard.
• so specifically, no image for each publication, and the text is to go fully across the page
• I don't know what lists look like in the template used, but we want a small space (1 line) between each entry - we want to keep this part short. if the bullet-pointed list has big gaps between bullets, then it is maybe better to have just one line per entry with \n between them
• font size currently used is good. Also the use of different font type and colour is a good idea. the explanation bit ("This paper is about...") could go in blue italics and the rest in the black normal. This presumably means having the explanation bit being in a different part in the json file (which is fine)
