Black Lives Matter

[bnb]

This PR adds a new handlebars template and sets index.md to use it. The intent (as discussed with the @nodejs/tsc and @nodejs/community-committee) is to redirect most/all pages to this page for a duration of 7 days from being moved into production. In local testing, this successfully set the main page of the english site to this (I presume we'd want to redirect all languages to this page rather than editing them all).

The template is not intended to be locked and can absolutely be modified - to add more names, to add more lists of Black people who have been murdered by the police, to add more TSC and CommComm names to the list of folks to reach out to, and to tweak phrasing/approach based on feedback.

Black Lives Matter.

@bnb my understanding from testing this locally is that there are no redirects. All deep links on the website will continue to work exactly the way the have prior to this PR.

This is likely preferred, as taking down nodejs.org/downloads would break node-gyp and a chunk of the internet.

I've locked this PR as the discussion has resolved and the update to the main page has landed.

As mentioned in the original post this decision was made with buy-in from both the TSC and the CommComm
