Beamer toc-depth not producing expected output

[darthlite]

Bug description

The toc-depth option does not seem to work when outputting to Beamer (just defaults to showing sections only).

Steps to reproduce

---
title: "Test"
format:
    beamer:
        toc: true
        toc-depth: 2
        slide-level: 3
---

# Section 1

## A subsection

### A slide

# Section 2

## Another subsection

### Another slide

Expected behavior

Should show subsections as part of the TOC since toc-depth: 2.

Actual behavior

Only shows sections in TOC:

Your environment

• IDE: VSCodium 1.80.1
• OS: MacOS Ventura 13.4.1 (22F82)

I believe this is a choice of Pandoc to hardcode in template the hideallsubsections option
See in template at https://github.com/jgm/pandoc/blob/e5fe3d5339170188f8eb236e7b53b19e29844b25/data/templates/default.latex#L510

$if(beamer)$
\begin{frame}[allowframebreaks]
$if(toc-title)$
  \frametitle{$toc-title$}
$endif$
  \tableofcontents[hideallsubsections]
\end{frame}
$else$

We use the same template in Quarto though we have a feature to overwrite part of a template using partials so you could tweak toc.tex partials - see https://quarto.org/docs/journals/templates.html#latex-partials

I would open a feature request in Pandoc to be able to customize this through an option - Though it seems toc-depth does not really apply to Beamer so they would need to also support it.

I can confirm that tweaking the toc.tex partial does the job. Thanks!

For Quarto, maybe the documentation page for beamer options could be updated to say it is not applicable (or maybe just removed)?

I have done that. Thanks for the suggestion
