Remove more mixOmics cross references

[DavisVaughan]

Apparently in #751 I somehow missed these two cross references to mixOmics

parsnip/man/rmd/pls_mixOmics.Rmd

Line 60 in ab3c94f

In this case, [plsmod::pls_fit()] has the same role as above but eventually targets [mixOmics::plsda()] or [mixOmics::splsda()] .

This caused hardhat to go through manual processing again 😢

We need to change:

[mixOmics::plsda()] or [mixOmics::splsda()]

to

`mixOmics::plsda()` or `mixOmics::splsda()`

and regenerate the documentation
