Enhance configuration

[antleblanc]

Hi!

First thank you for this project!

I've noticed some duplicate informations regarding the configuration.

Here is a suggestion, feel free to give me your feedback.

Before:

{
    "type": "github",
    "repository": "bnjjj/fixme_report",
    "token": "PERSONAL_TOKEN_FROM_GITHUB",
    "username": "bnjjj",
    "url": "https://github.com"
}

After:

{
    "type": "github",
    "repository": "bnjjj/fixme_report",
    "token": "PERSONAL_TOKEN_FROM_GITHUB"
}

Notice that here both username and url are removed because it can be infer from both type AND repository.

See: https://github.com/bnjjj/fixme_report#configuration

[bnjjj]

Agree for username. But not for the URL. (For example in case of Github enterprise).

By the way, this project just started so it's in their very early stage. So if you find a better way to document, or a better usage feel free. Next step for me is to try and play with github action to make automatic release when I bump version in cargo.toml
