Package xcolor Error: Undefined color `fgcolor'.

These reports on the Bioc-devel mailing list https://stat.ethz.ch/pipermail/bioc-devel/2024-June/020463.html suggest a recent change in xcolor (???) that needs to be addressed in BiocStyle::latex()

The issue persist if I use texlive 2023 (which has the old xcolor package from 2022). It seems to me that the highr update from 0.10 from 0.11 created the problem. knitr released 1.4.7 to address some the compatibility issues.

Downgrading highr to 0.10 and knitr to 1.4.6 also fixes the issue posted on Bioc-devel.

I see this commit yihui/knitr@4c6978e from several years ago; perhaps this is a regression?
