Support cookbook in `connectapi`: Viewing Available Python, R, and Quarto Runtime Versions

[toph-allen]

https://docs.posit.co/connect/cookbook/server-management/viewing-available-python-r-quarto-runtime-versions/index.html

There is actually already a client$server_settings_r() function, already, but it literally just gets the server settings endpoint and spits out a list — it doesn't do anything to the resulting data.

> client$server_settings_r()
$installations
$installations[[1]]
$installations[[1]]$version
[1] "3.0.0"

$installations[[1]]$cluster_name
[1] "Local"

$installations[[1]]$image_name
[1] "Local"


$installations[[2]]
$installations[[2]]$version
[1] "3.0.1"

$installations[[2]]$cluster_name
[1] "Local"

$installations[[2]]$image_name
[1] "Local"

Provide a new function to get all runtimes.

> get_runtimes(client)
   runtime version
1   python   3.8.1
2   python   3.9.7
3   python 3.10.10
4   python  3.11.3
5   python  3.12.4
6        r   3.6.3
7        r   4.0.5
8        r   4.1.1
9        r   4.2.3
10       r   4.3.1
11       r   4.4.0
12  quarto 1.4.557
13  quarto  1.5.55

Possibly filter by language.

> get_runtimes(client, "r")
   runtime version
1       r   3.6.3
2       r   4.0.5
3       r   4.1.1
4       r   4.2.3
5       r   4.3.1
6       r   4.4.0

Other notes.

• Should probably be returned as a tibble. These examples show a data frame just because that's what some existing code does.
• Deprecate the old function.
• Is the name get_runtimes good? get_server_runtimes() might be clearer.
