Kotlin documentation cleanup

[cosinekitty]

The Dokka tool generates incorrect references to properties. For example, in source/kotlin/doc/-aberration/-corrected/index.md:

//[astronomy](../../../../index.md)/[io.github.cosinekitty.astronomy](../../index.md)/[Aberration](../index.md)/[Corrected](index.md)

# Corrected

[jvm]\
[Corrected](index.md)()

Request correction for aberration.

## Properties

| Name | Summary |
|---|---|
| [name](../../-node-event-kind/-ascending/index.md#-372974862%2FProperties%2F-1216412040) | [jvm]<br>val [name](../../-node-event-kind/-ascending/index.md#-372974862%2FProperties%2F-1216412040): [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html) |
| [ordinal](../../-node-event-kind/-ascending/index.md#-739389684%2FProperties%2F-1216412040) | [jvm]<br>val [ordinal](../../-node-event-kind/-ascending/index.md#-739389684%2FProperties%2F-1216412040): [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) |

It does not make sense to link to NodeEventKind.Ascending from Aberration.Corrected. They are both enums, but they have nothing to do with each other.

I may want to open an issue on the Dokka project, but in the meantime, I will add a cleanup step to the script generate/kotlindoc/format_kotlin_doc.py.

I also want to strip out the [jvm] part.

I submitted an issue on the Dokka project for the unwanted Markdown for the name and ordinal properties that link to the wrong class.

I'm also going to make format_kotlin_doc.py strip out internal enum initializers. For example, it will transform:

[Mars](index.md)(MARS_GM, 686.98, VsopModel(vsopLonMars, vsopLatMars, vsopRadMars))

to

[Mars](index.md)

That stuff is internal code, and should not be exposed as public documentation.

[cosinekitty]

I found and reported another issue: enum members are listed in backwards order.

[cosinekitty]

Yet another issue I just reported: documentation includes internal source code for enum constructor calls.

I made a series of changes to work around these issues, ending with d130405. I think the documentation is in reasonable shape for now.
