The RDEPEND in texlive-latexextra on dev-tex/minted was a convenience
dependency because minted used to be bundled.
Unfortunately, we get a cycle:
```
(dev-tex/minted-2.9:0/0::gentoo, ebuild scheduled for merge) depends on
(dev-texlive/texlive-latexextra-2023_p69752-r4:0/0::gentoo, ebuild scheduled for merge) (runtime)
(dev-tex/minted-2.9:0/0::gentoo, ebuild scheduled for merge) (runtime)
```
Drop the minted dep to PDEPEND given we don't actually need it
for texlive-lateextra to build, it's just a convenience dep.
