chore: Update license

[jeeyyy]

Update license to match https://www.w3.org/Consortium/Legal/2015/copyright-software-and-document

[nitedog]

Do we need to copy the license text or is it sufficient to provide the license name and link? W3C has persistent links, so there should be no problem in my little understanding of licensing.

Updated.

@nitedog this is not just a link, I have copied over the text.

@JKODU sorry if I was not clear -- I'm proposing to simply link to the license rather than to copy and paste the text. What is the reason for copying the license text? This creates confusion and headache in my view (people have to actually compare if it is the same license text etc.).

@nitedog

The reason for copy/ pasting the text is that, if and when the original license changes, it does not change the license on this repo automagically.

Any license changes will be done via a PR, which will help notify and communicate of such changes.
