Doublons in contributors list

What needs to be fixed?

First, I'm not too proud of this, this is very stupid glitch, but that's it. I was just curious about rust contributors list
(like this one : https://thanks.rust-lang.org/rust/1.51.0/)

I was looking for French names and I found some relatively unusual French-like names several times like "Amanieu d'Antras" which appear at positions 61 and 88.

This can be found using this script:

w3m -dump https://thanks.rust-lang.org/rust/1.51.0/|awk -F"  " '{print $2}'|sort|uniq -c|grep -v 1

which answers:

     20 
      2  Amanieu d'Antras
      2  Ashley Mannix
      2  Ian Jackson
      2  Ryan Scheel
      2 Bastian Kersting
      2 Tristan Dannenberg
      2 Weihang Lo

Page(s) Affected

Nearly all on thanks.rust-lang.org but definitively:

https://thanks.rust-lang.org/rust/all-time
https://thanks.rust-lang.org/rust/1.51.0/
https://thanks.rust-lang.org/rust/1.50.0/
https://thanks.rust-lang.org/rust/1.49.0/
https://thanks.rust-lang.org/rust/1.48.0/
https://thanks.rust-lang.org/rust/1.47.0/

Suggested Improvement

Merge the homonymous lines numbers.

Reproduce the duplicate names with the provided w3m/awk/sort/uniq/grep command and compare the affected thanks.rust-lang.org pages, especially the all-time and Rust 1.47.0–1.51.0 lists. Trace the contributor-list generation entry point, then verify that homonymous entries are merged with their line numbers represented correctly and that the listed pages no longer show duplicate names.
