replace import url for less.js with local lib

[DK101010]

Our Browser they have access to Cloudstack runs in a isolated environment with restricted access to the internet . Therefore runs Cloudstack into a timeout while it tries to loading less.min.js and the result is that it takes a very long time for the login page to load.

Lib: https://cdnjs.cloudflare.com/ajax/libs/less.js/2.7.2/less.min.js

I want to replace this lib with a local version but I have no clue how.

This Lib will be added during the build in the index.html an I guess it comes from a node module.
Install of the less.js with version 2.7.2 via npm runs into an error during the build.

The https://cdnjs.cloudflare.com/ajax/libs/less.js/2.7.2/less.min.js is default loaded by antd-theme-webpack-plugin
It is possible to use an url or path as option lessUrl (should be added in ui/theme.config.js).

So easiest solution would be to download https://cdnjs.cloudflare.com/ajax/libs/less.js/2.7.2/less.min.js during build, place it in <webroot>/js and refer it as relativ path in lessUrl 🤔
but honestly, I'm not familiar with the UI build process, those do not have any glue how to download the file during build and place it accordingly 🙈

Created a PR, which add a local copy of less.min.js and use it in lessUrl
