PDK: incorrect example of invocation of `pdk get config`

[hbrown-uiowa]

Describe the Bug

Sample code is incorrect on https://www.puppet.com/docs/pdk/3.x/pdk_reference
The documentation lists this as the example for getting a config value: pdk config get user.module_defaults.author
If I run the command, I get pdk: unknown command 'config'

Expected Behavior

I expect to see the value of user.module_defaults.author.

Steps to Reproduce

Steps to reproduce the behavior:

1. pdk new module foo
2. cd foo
3. pdk config get user.module_defaults.author

Environment

• $ pdk --version
  3.3.0

• Fedora 40

Additional Context

The documentation for 2.x has a similar problem and also tries to reference a key that does not exist

$ pdk get config user.analytics.disabled
pdk (ERROR): Configuration item 'user.analytics.disabled' does not exist
