AsciiDocPropertyReferenceWriter is not reproducible

Given the same inputs, the generated `config-properties.adoc` file might be different.

While working on refactoring the `micronaut-core` build, I wrote an utility to check that the generated jar files were the same byte-to-byte before and after the migration. I noticed that it wasn't the case because of 2 files:

- `config-properties.adoc`, generated by this project
- `spring-configuration-metadata.json`

Here's a file generated in a first round:

Notice that while the contents is the same, the order of sections differ.

Read AsciiDocPropertyReferenceWriter and reproduce generation of config-properties.adoc with identical inputs; compare the section ordering across runs. Done means repeated generation produces stable ordering and byte-identical output.
