Change devDependency to dependency

You have d3-scale as a devDependency for nivo legends https://github.com/plouc/nivo/blob/master/packages/legends/package.json#L27

When we try to run your basic “hello world” examples we got:

Cannot find module 'd3-scale' from '../../node_modules/@nivo/legends/dist/nivo-legends.cjs.js'

    Require stack:
      /my-project/node_modules/@nivo/legends/dist/nivo-legends.cjs.js
      /my-project/node_modules/@nivo/line/dist/nivo-line.cjs.js

This should be moved to dependency or added as a peerDependency (preferably the former), otherwise it requires the user of Nivo to debug this. Naively one may try to install d3-scale in their package.json which will cause even more issues since the latest major version of said package is relying on experimental node features which will throw nonsensical errors taking the user further down the rabbit hole.

I believe this one small fix will greatly improve the DX for this library.

The code you publish in your dist for legends does a require("d3-scale") so this is not a devDependency.

If using Yarn 2/3 berry you can add this temporary workaround to .yarnrc.yml which clears up the error (don’t forget to rerun yarn install after adding it):

# .yarnrc.yml

...

packageExtensions:
    '@nivo/legends@*':
        dependencies:
            'd3-scale': '*'
            '@nivo/colors': '*'
...

This only worked for me if declared as peerDependencies (possibly because I had both of them as dependencies in my package.json already):

...
 packageExtensions:
     '@nivo/legends@*':
         peerDependencies:
             'd3-scale': '*'
             '@nivo/colors': '*'
 ...
