Remove ruleset for printing AST

[paul-dingemans]

This issue originates from a discussion starting with this comment.

Ktlint CLI allows printing of the AST of a file or a piece of code via option --print-ast. Also it is possible to print the AST in unit tests by setting environment variable KTLINT_UNIT_TEST_DUMP_AST. The value of this functionality is very low compared to using the IntelliJ IDEA plugin PsiViewer.

@paul-dingemans could you also publish a new version of com.pinterest:ktlint which is used by org.jlleitschuh.gradle.ktlint for example.

ktlint-ruleset-test-tooling is still in the latest version 0.49.0-20230328.095730-189.
(https://oss.sonatype.org/content/repositories/snapshots/com/pinterest/ktlint/0.49.0-SNAPSHOT/ktlint-0.49.0-20230328.095730-189.pom)

As a result of an uninteded change, all snapshots starting from PR #1898 have been published to a different location. This will be fixed with #1929. In the 1.x release of ktlint we will switch to the new group coordinates.
