Error generating Quarto manifest due to hanging get_python_env_info() argument

[wilssh]

Bug Description. Using rsconnect-python==1.21.0 to generate a manifest for a Python-based Quarto project:

rsconnect write-manifest quarto .

leads to error

Checking arguments...                            [OK]
Inspecting Quarto project...                     [OK]
Inspecting Python environment...                 Traceback (most recent call last):

    yield
  File "my-proj/venv/lib/python3.8/site-packages/rsconnect/main.py", line 1716, in write_manifest_quarto
    python, environment = get_python_env_info(base_dir, python, False, force_generate)
TypeError: get_python_env_info() takes from 2 to 3 positional arguments but 4 were given
[ERROR]
Internal error: get_python_env_info() takes from 2 to 3 positional arguments but 4 were given

Steps to Reproduce. Create a Quarto project with _quarto.yml contents:

project:
  title: "my-proj"

and my-proj.qmd contents:

---
title: "my-proj"
---

```{python}
print("Bug reprex.")
```

Then try to generate a manifest with rsconnect-python==1.21.0:

rsconnect write-manifest quarto .

Expected Behavior. With rsconnect-python==1.20.0, the output is as expected:

$ rsconnect write-manifest quarto .
Checking arguments...                            [OK]

Creating manifest.json...                        [OK]

Additional context. @adamwangdata and I deploy Git-backed content onto our Connect Server.
We recently upgraded to rsconnect-python==1.21.0 and have had issues generating manifest.json for Python-based Quarto documents.

We suspect this is due to the removal of the Conda flag and the lingering reference to it here:
https://github.com/rstudio/rsconnect-python/blob/5c8a21e504ccef4dc566ec7a14d317c76e7d2deb/rsconnect/main.py#L1775

Removing the third False argument alleviates the issue. Also related: #522.
