Fix trailing lambda with chained call indentation (#589)

[ptitjes]

This PR fixes the indentation of trailing lambda with chained calls.
See #589.

I used an AI agent to understand how ktfmt and google-java-format work. This PR has been implemented with the help of an AI agent. I don't know much about the PSI AST shapes, so I wouldn't be surprised if the AST tests and visits are not general enough, or simply wrong.

This said no internal changes here. Which is odd, I was expecting a bunch of them.
Tomorrow I'll do some extra validation of it, but just wanted to let you know this much already

[ptitjes]

@hick209 tell me if you need me to add more tests or fix something.

[hick209]

Oops, look at me not keeping my promises. Sorry about that, will look at it again right now!

[hick209]

Yes, this is incomplete as I suspected.

Here's the test I made, which I thought should happen the other way around

  @Test
  fun nivaldo_test() {
    // this passed
    assertFormatted(
        """
        |fun quux() {
        |  runnnnn {
        |        foo()
        |        bar()
        |      }
        |      .baz()
        |}
        |"""
            .trimMargin()
    )

    // this failed
    assertFormatted(
        """
        |fun quux() {
        |  runnnnn {
        |    foo()
        |    bar()
        |  }
        |      .baz()
        |}
        |"""
            .trimMargin()
    )
  }

Please LMK if I'm missing something here.

Also don't forget to update the CHANGELOG.md so I don't forget to give you proper attribution

Hmmm, sorry, it seems I forgot half of the issue... I fixed it and added a bunch more tests.
Also fixed it to use the continuation indent for chained calls (and not the block indent as it was before).

Done.

I applied the new formatting (1 change in KotlinInputAstVisitor.kt) in a separate commit, so that you can see the changes. Now I expect you will have more changes on your internal projects...

It still says no changes in our mega repo 🤔

Maybe we are missing something here. Let me test it out further to see if we are missing any use case

Edit: This might actually be a bug on our end here. I'm investigating
Edit 2: My script was too narrow and this pattern is not all that wide spread. That's why it was not caught. Seems like we are good now!

Thanks for the awesome work!
