Upgrade ktlint and switch to the non-experimental TrailingCommaOnCallSiteRule & TrailingCommaOnDeclarationSiteRule

[Hexcles]

ktlint has graduated TrailingCommaRule from experimental to standard ruleset, while splitting it into two rules: TrailingCommaOnCallSiteRule & TrailingCommaOnDeclarationSiteRule.

There is a practical benefit for having them separate, as you'll be able to enforce one kind while ignoring the other (in a sense, making the current settings for TrailingComma "nullable", which can, for example, help to work around issues like pinterest/ktlint#1557 by opting out of TrailingCommaOnCallSiteRule while still keeping TrailingCommaOnDeclarationSiteRule.

Thanks for raising! I'm closing as this is effectively a duplicate of #5281, and will be addressed by #5312 which should hopefully be included in the final 1.22.0 detekt release.
