Fix up REFs

[CaptainSifff]

All over the paper there are numerous REF instances missing. I list here some (line numbers relative to the main branch tex code):

• [x] 38
• [x] 39
• [x] 59 (Why is RS different than data)
• [x] 61
• [x] 65 (RS Policies)
• [ ] 103 Charite
• [X] 107 (low quality)
• [ ] 113 (update: was 119)
• [ ] 136 SuccessStory Carpentries https://carpentries.org/testimonials/
• [ ] 155 no ref?
• [X] 160
• [X] 171 welcome trust or others? (update: commented out)
• [X] 172 CHORUS? Nature? (update: gone)
• [x] 133 apples to apples?
• [X] 253
• [X] 254
• [ ] 255 (update: was 262)
• [X] 263 Code Clinic
• [ ] 268 (update: was 280)
• [ ] 300 (update: was 311)
• [x] 343 twor refs , github and zenodo

All missing items reflect tex-line numbers as of 25.04.24 of branch main.

Unfortunately, the above mentioned line numbers are slowly diverging, but you can always find them by looking for REF in the document.

@jlinx started fixing some of these in #26.

I can work on that.

I've updated the line numbers.

I updated the line numbers based on the changes of two weeks ago.
