Sub-modules don't inherit the footer message for HTML Dokka docs

[EdricChan03]

It appears that sub-modules don't inherit the footer message defined from the root module's pluginConfiguration.html block:

plugins {
  dev.adamko.`dokkatoo-html`
}

dokkatoo {
    pluginsConfiguration.html {
        // ...
        footerMessage.set("&copy; 2023 <...>")
    }
}

• Root docs page
• Sub-module docs page

Thanks for the report!

I suspect that customising the footer has to be done in the aggregating project, and this is a limitation of the Dokka HTML plugin, which Dokkatoo doesn't 'own'. But that's a suspicion, I'd have to look through the Dokka HTML plugin code to verify.

It looks like my suspicion was right: Kotlin/dokka#2419

Dokkatoo could add some notes to the KDoc of the HTML plugin options to try to help, which isn't great (because it would still be possible to make a mistake) but I don't think anything else is possible. What do you think @EdricChan03?
