Rollup merge of #93231 - conradludgate:doc-link-brightness, r=notriddle

adjust sidebar link brightness

Fairly simple change. I've taken the existing link colour and main body background colours, and made sure that the sidebar+link contrast is the same.

ayu:
- [main content contrast](https://colourcontrast.cc/0f1419/39afd7) - 7.31
- [current sidebar contrast](https://colourcontrast.cc/14191f/39afd7) - 6.97
- [new sidebar contrast](https://colourcontrast.cc/14191f/56b1d9) - 7.30

dark:
- [main content contrast](https://colourcontrast.cc/353535/d2991d) - 4.86
- [current sidebar contrast](https://colourcontrast.cc/14191f/d2991d) - 3.19
- [new sidebar contrast](https://colourcontrast.cc/14191f/fdbf35) - 4.87

light:
- [main content contrast](https://colourcontrast.cc/ffffff/3873ad) - 4.97
- [current sidebar contrast](https://colourcontrast.cc/f5f5f5/3873ad) - 4.56
- [new sidebar contrast](https://colourcontrast.cc/f5f5f5/356da4) - 4.97
