Setup prettier (#6758)
* Add prettier as a dependency

* Add format command and configure prettier

I opted for single quotes to be in line with other simple-icons projects

I ignore the data file because changing its formatting is quite a bit of
trouble for all open PRs.

* Run prettier

* Replace all functions by arrow functions

* Move prettier configuration to config file

Move it to a file so editors (and other software) can pick up on the
configuration. I went with .js because (a) it allows for comments and
(2) it seems most of the config files are in JavaScript already.

* Add prettier --check when running npm run lint (This adds it to the CI as well)

* Add husky and format changes before committing

* Use object destructuring for imports consistently

* Add shebang and fileoverview to jsonlint.js
