pdflatex extension should be updated for Inkscape 1.3 CLI change (pdf-pages to pages)

Steps to reproduce:

• open Inkscape
• Run Extension > Render > Formula (pdflatex) default

What happened?

• Extension fails, error message is essentially Unknown option --pdf-page=1

What should have happened?

• No error

Note: CLI option change in inkscape!4691 (merged)

Inkscape Version and Operating System:

• Inkscape Version: Inkscape 1.3-dev (a43e0c1cdb, 2022-09-21) Linux Mint 20
• Didn't test with latest extensions, but looking at it, it still uses pdf_page https://gitlab.com/inkscape/extensions/-/blob/80a9dd96e30995367c577048fa27872c047b1997/pdflatex.py#L82 (looks like the only use of pdf.page, searching through share/extensions)
