Some engine combinations trigger unexpected tlmgr updates

Bug description

Using

-M pdf-engine:latexmk -M pdf-engine-opt:-outdir=/tmp/out

without first disabling the built-in engine with latex-auto-mk: false triggers:

Rendering PDF
running latexmk - 1
  Rc files read:
    NONE
  Latexmk: Nothing to do for 'test.tex'.
  
  
updating tlmgr

updating existing packages

I admit this is a weird combination of options, but a quite similar one is given in the documentation:

pdf-engine: lualatex
pdf-engine-opt: -outdir=out

So perhaps this should be clarified in the documentation, rejected from the command line or made to work somehow.

Steps to reproduce

For a dummy test.qmd document run:

quarto render test.qmd -t pdf -M pdf-engine:latexmk -M pdf-engine-opt:-outdir=/tmp/out

Then try it again disabling the built-in builder:

quarto render test.qmd -t pdf -M latex-auto-mk:false -M pdf-engine:latexmk \
    -M pdf-engine-opt:-outdir=/tmp/out

Expected behavior

If this is not expected to work, clarify it in the documentation and rejected the combination from the CLI. Otherwise make it work properly. It shouldn't start any updating process.

Actual behavior

Shown above.

Start with the alternate PDF engine documentation and reproduce the two quarto render commands using pdf-engine, pdf-engine-opt, and latex-auto-mk. Trace how these options select the LaTeX builder and trigger tlmgr; done means the combination no longer starts an update process, or the documentation and CLI clearly reject or explain it.
