ToC corrections & image edits

• P6 - image caption to be added: Celebrating a decade of gravitational-wave astronomy from GW150914 (top) to GW231123 (bottom). Find out more about GW231123 on pp. 24-26.
• P6 in David’s text, would it be possible to add a footnote explainer for DetChar (no worries if not): "Detector Characterisation Working Group”
• P7. - replacement caption: Gaby González and Fulvio Ricci cutting the GW150914 celebration cake at the LIGO-Virgo Collaboration (LVC) meeting in Pasadena (March 2016).
• P7 - Nutsinee’s text - suggest moving surname fully to the next line to avoid the break in Kijbunchoo
• P. 8 - Same for Sathyaprakash - suggest moving surname to next line to avoid the break if possible
• P11 For Sam’s entry - only if possible, add "formerly Birmingham” after Sam’s name (don’t worry about it if this causes problems).
• P12 - Delete “University of Florida” from Dave’s affiliation
• P15 - image caption, replace “our Cardiff” -> “the Cardiff”
• P16 - Typo in Barry’s surname: “Barrish” -> “Barish”
• remove m00090 as it's effectively a duplicate of m0096. The caption for m0096 can be something like "Even a black hole enjoys eating cake on it's birthday, so here is a drawing of the remnant black hole from GW150914 devouring it's birthday cake, candles and all, 10 years after it was formed."
