Rollup merge of rust-lang#65665 - tspiteri:italic-and-update-SourceCodePro, r=GuillaumeGomez

Update Source Code Pro and include italics

Fixes rust-lang#65502.

A few notes:
  * As stated in rust-lang#65502, this does increase the download size.
  * Since this PR changes the font set, I think docs.rs would have to be updated if this PR is merged.
  * The fonts have a double extension (.ttf.woff); this is to keep the names consistent with the upstream font release which does that to distinguish these from the .otf.woff files ([Source Code Pro otf renders poorly on older Windows system apps](adobe-fonts/source-code-pro#25 (comment))).
