Feature reuqest: template support

[labuladong]

Thanks for this excellent plugin! I wonder if we can add a feature that allows users to copy links with templates.

For example, if I'd like to copy links in markdown format, I could set this template: [${file.name}](${git-link}).

I also think this can be beneficial! Would love to work on that feature, and contribute 👨‍💻

This can be a settings under the Advanced settings section with a dropdown of predefined templates, or custom template:

I also would like to be able to copy markdown links. Whether that is through templates or not doesn't matter to me.

You should be able to copy markdown links already
