Trailing comma defaults changed in 0.48

[Spikhalskiy]

Expected Behavior

With the default ruleset ktlint shouldn't add trailing commas on the call and declaration sites.
It's the behavior with 0.47
It's the specified behavior in the doc:
https://pinterest.github.io/ktlint/rules/configuration-ktlint/#trailing-comma-on-declaration-site
https://pinterest.github.io/ktlint/rules/configuration-ktlint/#trailing-comma-on-call-site

Observed Behavior

After upgrading from 0.47.x to 0.48.{0,1,2}, applying ktint reformatted code to add trailing to declaration sites.
To preserve an old behavior I had to add

# ij_kotlin_allow_trailing_comma = false
# ij_kotlin_allow_trailing_comma_on_call_site = false

to '.editorconfig' while it shouldn't be necessary, these values are stated as defaults.

Your Environment

• Version of ktlint used: 0.47.1, 0.48.{0,1,2}

• Relevant parts of the .editorconfig settings

  • 0.47.x:

  root = true
  
  [*.{kt,kts}]
  indent_size = 2
  

  • 0.48.{0,1,2} to save an old behavior:

  root = true
  
  [*.{kt,kts}]
  indent_size = 2
  
  ij_kotlin_allow_trailing_comma = false
  ij_kotlin_allow_trailing_comma_on_call_site = false
  

• Name and version (or code for custom task) of integration used (Gradle plugin, Maven plugin, command line, custom Gradle task): diffplug/spotless:6.14.1

• Version of Gradle used (if applicable): 7.6

This change is documented in the release notes. Also see PR #1669

The default value for trailing comma's on declaration site is changed to true unless the android codestyle is enabled. Note that KtLint from a consistency viewpoint enforces the trailing comma on declaration site while default IntelliJ IDEA formatting only allows the trailing comma but leaves it up to the developer's discretion.

@paul-dingemans Thank you for the context! Should there be a follow-up update of the documentation on https://pinterest.github.io/ktlint/rules/configuration-ktlint?
