Update year from 2021 to 2024 in footer copyright

Updated the copyright year in the "message" field.

Type of change

PATCH: backwards compatible change

My current understanding is that the point of the © notice is to publicly demonstrate the year we began asserting ownership over bud.js. Obviously different people interpret this in different ways, but that's my own interpretation.

Thus, © 2021 is what we use in the footer.

Alternatively, many sites use a range of dates, which in our case would be © 2021-20XX, with the end date auto-updating. But, the end date is really not important. The copyright is valid for 70 years from the time of first publication. In other words, just a bare © 2021 inherently signifies © 2021 - 2091. This would also be my argument against the proposed change in this Pull Request.

We actually inherited this from Docusaurus. Their reasoning is the same as mine, more or less.

Again, this is based on my interpretation of US copyright law, and I'm obviously not a lawyer. cc @retlehs who might disagree with me. I don't care that much, as fundamentally copyright is legally recognized to be inherent to creation and our website © notice isn't even a particularly good way of demonstrating our ownership, legally.

👍 If we're going to modify this I'd want to just drop the copyright notice entirely. We removed it from the main roots.io site a while back.
