Update frontend dependencies

[magicznyleszek]

Description

Please use https://www.npmjs.com/package/npm-check-updates to see what packages are there to be updated (almost all of our dependencies have newer versions).

I tried going with ncu --upgrade --target minor to update only minor and patch versions, but it turned out to cause errors in npm run watch, so unfortunately it might require going one by one.

Additional information

This is unfortunately blocked by #3145 for at least a few of the dependencies. The issue is that some of them are requiring a fresher version of reflux or react than what we have. We would need to replace reflux with something else in order to be able to update react.

These ones require more work to adapt:

 coffeescript               ^1.12.0  →   ^2.5.1 
 css-loader                  ^1.0.0  →   ^3.5.3 
 eslint                      ^6.2.0  →   ^7.0.0 
 eslint-loader               ^3.0.0  →   ^4.0.2 
 file-loader                 ^2.0.0  →   ^6.0.0 
 react-dropzone              ^5.1.1  →  ^11.0.1 
 react-hot-loader             3.1.0  →  4.12.21 
 react-router                ^3.2.1  →   ^5.2.0 
 react-select                ^2.0.0  →   ^3.1.0 
 react-table                 ^6.8.1  →   ^7.0.5 
 select2           3.5.2-browserify  →   4.0.13

@magicznyleszek is this still relevant?

[magicznyleszek]

@joshuaberetta yes and no. We have still dependencies to update, but so much time passed that there are a lot more of them ;) I've updated the description, moved to proper column and unassigned myself 👍

Leaving a note to myself that I would love to have a up to date version of react router and eventually start using query params for things like filters. Newer react router makes it easier to set and fetch them. Since I'm already kind of working on an alternative to reflux, then I guess I'm working on this issue already 😃
