Default description is the project name

# Context

Hello

Based on the documentation https://opensource.deepmedia.io/deployer/configuration, I created the following configuration:
```
projectInfo {
// https://opensource.deepmedia.io/deployer/configuration
val projectName = rootProject.name
url.set("https://github.com/Hansanto/$projectName")
scm {
fromGithub("Hansanto", projectName)
}
}
```

But when I checked the published version: https://central.sonatype.com/artifact/io.github.hansanto/kault/1.6.1, the description is "kault" (the name of the project)

So, I tried to change to set the description based of the rootProject data:
```
projectInfo {
// https://opensource.deepmedia.io/deployer/configuration
val projectName = rootProject.name
description.set(rootProject.description)
url.set("https://github.com/Hansanto/$projectName")
scm {
fromGithub("Hansanto", projectName)
}
}
```
And the problem is fixed.

# What's the problem

On the documentation, there is information about default description:
```
// Project description. Defaults to rootProject.name
description.set("Handy tool to publish maven packages in different repositories.")
```
so, maybe there is a bug, or maybe the documentation Is outdated
