chore(poststylus): update all PostStylus dependencies and devDependencies

[Kristinita]

1. Summary

I updated PostStylus dependencies and devDependencies to make it compatible with Autoprefixer 10.0.

2. MCVE

2.1. Data

You can see it in the KiraPostStylus2020 branch of my debugging/demo repository.

• Gruntfile.coffee:

   module.exports = (grunt) ->
  
       grunt.loadNpmTasks 'grunt-contrib-stylus'
  
       postcss = ->
           require('poststylus') [
               'autoprefixer'
           ]
  
       grunt.initConfig
  
           stylus:
               options:
                   compress: false
                   linenos: false
                   use: [postcss]
               themecompile:
                   files: [
                       src: 'KiraPostStylus.styl'
                       dest: 'KiraPostStylus.css'
                   ]
  
       return

• KiraPostStylus.styl:

   .KiraExample
       display grid
       transition all .5s
       user-select none
       background linear-gradient(to bottom, white, black)

2.2. Before

• .travis.yml:

   os: linux
  
   dist: focal
  
   git:
     depth: 1
  
   language: node_js
  
   node_js:
   - node
  
   install:
   - npm install -g grunt-cli
   - npm install
  
   script:
   - grunt stylus --verbose

• Travis build failed:

  Warning: [object Object] is not a PostCSS plugin� Use --force to continue.

2.3. After

• .travis.yml:

   os: linux
  
   dist: focal
  
   git:
     depth: 1

   - npm install
   - npm-check node_modules/poststylus -y
  
   script:
   - grunt stylus --verbose
   - cat KiraPostStylus.css

     transition: all 0.5s;
  
     -webkit-user-select: none;
  
        -moz-user-select: none;
  
             user-select: none;

   }

LGTM, thanks!

@seaneking , please don’t forget to publish the version with new changes to npm (in my practice, developers who have accepted a pull request often forget to do this).

Thanks.

Yes I've released a new version
