Bump autoprefixer from 7.2.6 to 9.0.0 in /front-end

[dependabot-preview]

Bumps autoprefixer from 7.2.6 to 9.0.0.

Release notes

Sourced from autoprefixer's releases.

9.0 “A Mari Usque Ad Mare”

Autoprefixer 9.0 brings Browserslist 4.0 and drops Node.js 4 support.

Breaking Changes

We removed Node.js 4 and Node.js 9 support since it doesn’t have security updates anymore.

We removed IE and “dead” browsers (without security updates) from Babel’s targets. Don't worry, Autoprefixer still generate IE-compatible code. These changes affect websites which run Autoprefixer on client-side like CodePen.

not dead
not Explorer 11
not ExplorerMobile 11
node 10
node 8
node 6

Autoprefixer Rails 9.0 dropped the RubyRacer and Sprockets 3 support.

Browserslist 4.0

Autoprefixer 9.0 uses Browserslist 4.0 to get your target browsers.

Now you use Browserslist to specify Node.js versions. Babel 7 will use Browserslist config as well.

Also, Browserslist 4.0 will warn you if you didn’t update Can I Use DB for last than 6 month.
