Set default "config_precendence" to "file-override"

[shuLhan]

If user have custom file type plugin that set "parser" option, calling
":Prettier" will return error "Prettier: failed to parse buffer".

This was caused by running prettier with CLI option "--parser X" with
"--config-precedence prefer_file" will cause prettier to ignore the
"parser" option.

I would like to investigate prettier cli itself. It sounds like a regression. Note that https://prettier.io/docs/en/cli.html#config-precedence

prefer-file
If a config file is found will evaluate it and ignore other CLI options. If no config file is found CLI options will evaluate as normal.
This option adds support to editor integrations where users define their default configuration but want to respect project specific configuration.

file-override will be the default behaviour on release/1.x but will test this PR. If it works I may merge it sooner in order to dogfood any potential issues prior to release

Also please note that on release/1.x we do not have a default 'parser' and do not pass parsers based on filetype! So that above issue should not occur.

Would you mind testing the release/1.x branch to see if your above problem is fixed ?

You can test that branch by adding to your .vimrc

Plug 'prettier/vim-prettier', {
  \ 'do': 'yarn install',
  \ 'branch': 'release/1.x',
  \ 'for': [
    \ 'javascript',
    \ 'typescript',
    \ 'css',
    \ 'less',
    \ 'scss',
    \ 'json',
    \ 'graphql',
    \ 'markdown',
    \ 'vue',
    \ 'lua',
    \ 'php',
    \ 'python',
    \ 'ruby',
    \ 'html',
    \ 'swift' ] }

Still does not work. I will create new issue to describe the problem in detail.
