First pass of cleaning SEEK4science

[PhilReedData]

First pass working through seek4science/seek-documentation#42 improvements across the SEEK4science website, agreed with Stuart and Munazah. I have done the following so far.

• Home page
  • Update screenshots
• About page
  • Remove the citing SEEK content.
  • Update PALS section, better phrasing
  • Link to FAIRDOM site pages for more details
• Get page
  • At the bottom, move the publications, cite examples here
  • For more publications, link to FAIRDOM site pages
• Publications page
  • Remove page
• Registration page
  • Remove page
• Contact us page
  • Update, remove Google Groups bit
• Docs page
  • Update to reflect the latest structure of the docs site (user guide, technical guide)
• Other pages
  • Fix broken links eg rightmove

I will continue to do (in the coming days, not a blocker for this first PR):

• Features page
  • Update with new features

The issue includes some additional tasks to do after this round that will take more time.

If I am granted access to make and merge branches on the parent repo please, that will be easier.
