Add Bearer Token Authentification

[Guuz1]

Hello Jack Gaino!
I researched a tool to use in a pipeline CI/CD in order to update docs from .md files into Confluence and your tool work very well! But in need for security I wanted to use Personal Token (that can be generated under the personal settings). This is a better approach for me.
So I decided to develop this feature by myself and here I am :D

To add this feature I needed to a little bit refactoring your code as you can see. Maybe one day this code will support OAuth too or an other authentification as-well!

I supposed that will be a minor update so I putted in my version the 1.3.0 but don't hesitate to change it if it not fit your versions organization.

The code was tested with of course the new --bearer-token arg but work as-well with --username arg

Let me know if you're ok with this change and I hope this will be helpful :)

Hi Gaël! I'll take a look at the merge request and leave some feedback :)

I took a look at your code. I really appreciate the contribution!

I'd rather not split out the MinimalConfluence object into two subclasses, and there are a couple other things that didn't quite sit right with me. If it's okay with you I'll re-implement this tonight on a separate feature branch, and you can try that out and let me know if it works for your use case.

I just implemented this and pushed a new version :) I tested it with a couple pages and it worked fine. If you have any issues feel free to open an issue!
