Rollup merge of rust-lang#93291 - conradludgate:minor-fix-93231, r=GuillaumeGomez

minor fix for rust-lang#93231

In rust-lang#93231 I introduced the new sidebar colours to make the contrast more balanced and easier to read, but it seems I made a copy-paste error in the light theme, resulting in functions appearing green.

This one line change replaces that colour with it's corrected orange/brown colour.

I have double checked the rest of the colours and they seem ok. Sorry for the inconvenience
