@material-ui/icons needs updating

[colemars]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

At least the Eco family of icons is missing from @material-ui/icons.

Expected Behavior 🤔

All Icons present at https://material.io/resources/icons are present in @material-ui/icons.

Context

I don't mind making a pull request - but I saw in the commit history there is a script you run to update the icons.

Unfortunately, I can't get the script to work for me. Looks like the URLs that are being fetched (Ex: https://material.io/resources/icons/static/icons/outline-accessible-24px.svg) aren't valid anymore.

Looks like some Icons present in https://material.io/resources/icons are not present in https://material.io/resources/icons/static/data.json.

Given that, I'm not sure much can be done with the script.

Moving the discussion to #12251

[colemars]

@oliviertassinari that discussion seems to be focused around size and icons that have been completely removed (not available at material.io any longer), no?

That isn't the issue here.

We can extend the scope. If the issue was only about old icons missing, we could close it, this legitimate that it stays open.
