Rollup merge of #80705 - tspiteri:italic-and-update-SourceCodePro, r=GuillaumeGomez

Update Source Code Pro and include italics

Fixes #65502.

#65665, a similar PR to this was merged but reverted because of #65665 (comment).

The issue in that comment is the upstream issue adobe-fonts/source-code-pro#217 which should now be fixed in the upstream since [2.032R-ro/1.052R-it/1.012R-VAR release](https://github.com/adobe-fonts/source-code-pro/releases/tag/2.032R-ro/1.052R-it/1.012R-VAR), so I think this can now be merged.

A couple of notes from the original PR:
* 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).
