Server Side Compiler doesn't import some remote CSS files

[viniciusfabri]

Preconditions (*)

1. Blank Magento 2.3.2, 2.3-develop with a custom theme(or just Luma)
2. Server side compiling enabled
3. PHP 7.1.26 & 7.2

Steps to reproduce (*)

1. On a .less file, import the following URL, according to the documentation:
   @import url("https://fonts.googleapis.com/icon?family=Material+Icons");
2. Clear pub/static/*
3. Run bin/magento setup:static-content:deploy -f

Expected result (*)

1. The LESS code should be compiled successfully

Actual result (*)

1. You get the following error:
   [2019-10-17 11:21:16] report.ERROR: File https://fonts.googleapis.com/icon not found. in styles-l.less [] []
   

Root cause

We were able to track down the issue down to the less.php library. This URL doesn't work because it doesn't have the "css" word in it, which the library takes into account when importing css files: https://github.com/wikimedia/less.php/blob/master/lib/Less/Tree/Import.php#L44

Not sure how we can fix this in Magento (the library project doesn't have an issue queue), so maybe we can update the documentation instead?

I couldn't find a similar ticket to this, but maybe it's a duplicate. If so feel free to close
