Rename `tex` output to `output-file` when `keep-tex: true`

[cderv]

Takes this qmd test.qmd

---
title: "Test"
format:
  pdf:
    output-file: pdf.pdf
keep-tex: true

# Test

This will produce a test.tex and a pdf.pdf output.

I think it could be better to have the intermediate be renamed to the output-file option when provided. 🤔

Opening this issue to track the idea and look into what we can do.

i would appreciate having this change as well !

This would certainly be nice.

For other coming here:

See the related discussion with a temporary "workaround" via specify format:latex (#10224 (reply in thread)) together with format:latex:output-file.

This would be a really useful feature. I am working in a project where I need an arxiv version of both the tex and pdf files as well as a journal specific version. While using different format blocks and using --to arxiv-pdf and --to journal.pdf I can produce two differently named pdf files, I still have to rename the tex file manually for one of them.
