params should work with `metadata-files`

NOTE:
I am using the quarto R package version 1.0 and quarto version 0.9.80
I found the version by running this code: as.numeric_version(system2(quarto:::find_quarto(), "--version", stdout = TRUE))
Due to some IT restrictions I have not updated quarto to the most recent release, although I may be able to in the future.

I have multiple *.qmd files that I want to be parameterized. I want them to share parameters and default values by inheriting from a separate YML file.

For example, I have a file named test.qmd with this YML header:

---
title: "Test Quarto Report"
metadata-files:
  - _params.yml
---

Then, in _params.yml I have

---
params:
  p1: 1.0
  p2: "A"
  p3: TRUE
---

However, this does not work. When I run quarto render, I get an error for "object 'params' not found"

Is there anything I can do to inherit params? Is this not possible in quarto 0.9.80? If so, is it possible in a later release?

Thanks,
Scott
