Update config roots in README

[heyrict]

As I work on another issue in your project, I have found that workspace.getConfiguration('bibtex') seems to be located at coc.preferences.bibtex rather than coc.source.bibtex as you documented in README.md. Probably your documentation should be updated to the latest changes of coc.nvim.

Also, my humble suggestion: As many of the extensions store their config in coc.preferences.*, what do you think about moving list.source.bibtex.* to coc.preferences.bibtex in accordance with other extensions?

Thank you in advance.

I don't use coc.nvim anymore, which probably explains why the documentation is out of date. I want to make sure I understand here: everything listed as being stored in coc.source.bibtex is now in coc.preferences.bibtex? That should be an easy enough fix.

I can fix the other thing, too. The way coc.nvim handled configurations really bugged me when I wrote this, so I'm glad it's more logical.

Yes, that's it. I have not fully tested other keys (e.g. list.*) but they seem unchanged.

Thank you for maintaining this package even after your abandoning coc.nvim.

Sorry for not getting back on this sooner, but I just pushed a branch, pref-fix, that implements these changes. Would you mind testing that it's working and I can PR it into the master branch.

EDIT: I just opened a PR, which is referenced below.

Thank you for your update! I'm sorry for that I have provided the wrong information related to the config location change. Most plugins actually stored their configurations in the object root rather than in coc.preferences. I have pushed a PR (#24) to fix this.

Also, during my testing, changes in bibtex.triggerCharacters and bibtex.triggerPatterns did not have any effects in my settings. Can you give it a shot?
