Relax asciidoctor version constraints to work under asciidoctor 2.0

[ProgramFan]

This extension works under asciidoctor 2.0 and is useful. So it would be nice to relax the version constraints so that we have an asciidoc-to-latex convertor.

I also ran into a problem when using both asciidoctor-bibtex and asciidoctor-latex, which should be fixed here. Please accept this pull request and release a new version. :)

Wondering if/when this is going to be merged; this is exactly my use case. I've never used Ruby, so this took a moment to figure out.

Meanwhile, I figured that the latex and bibtex extensions should work together. See asciidoctor-bibtex readme:

it can be used together with asciidoctor-latex for native bibtex support

Anyhow, I can confirm this works on Windows 10. Thanks!

This project is currently seeking a maintainer to move it forward. See https://github.com/asciidoctor/asciidoctor-latex/issues/67. Although I've advised on the project, I've never been a maintainer of it, nor do I have time. But I will help with the administrative tasks necessary to get it moving again.

@mojavelinux Let us know when there is an update to this. asciidoctor-latex is a pretty important part of Asciidoctor.

If there's an update, you'll see it here. I don't have one. My offer stands that I'm willing to help by handling the administrative tasks if someone comes forward to maintain the code.
