Javadoc version number is always 0.0.1

[GlenKPeterson]

Describe the bug
Javadoc displays My-Module-Name My-Version-Number 'API' at the top of every page. I assume the Module-name is taken from settings.gradle.kts where it says rootProject.name = "My-Module-Name". I would expect the Version-number to be taken from build.gradle.kts where it says version = "0.0.14" but the version number always shows up as 0.0.1

Expected behaviour
I expected these version numbers to match.

build.gradle.kts source

version = "0.0.14"

index.html generated file

<h1 class="title">Indented 0.0.1 API</h1>

To Reproduce
Build this tiny Kotlin/Gradle project:
https://github.com/GlenKPeterson/Indented

Run with

./gradlew clean assemble dokkaJavadoc

Dokka configuration
None needed. Just use gradle defaults.
