Links in readme.md not working in certain editors

[nwawrzyniak]

Clicking any of the links in brackets in the file readme.md in a text editor like "Notepad++" links to a website with ")" appended to the link (e.g. instead of linking to "https://luarocks.org/" you link to "https://luarocks.org/)" since the closing bracket is not seperated by a space). This behaviour is seen with a lot of modern editors, so links should ideally end with a white space before the closing bracket.
