Add block bindings for copyright date and privacy policy link

[carolinan]

What

Add a block binding for a dynamic copyright date.
Add a block binding for a link to the privacy policy page. This link should only display if the privacy policy page is published.

Why

The purpose of this task is twofold: To solve two common problems and showcase how to use the block bindings api.

I'd love to see this.

I'd say the one downside of the Privacy Policy is that you'll get an empty <p> on the front end if it's not published because there's no good way to do conditionals. I know there's some discussion around this here (not sure if there's a dedicated ticket, though): WordPress/gutenberg#59272 (comment)

Perhaps the paragraph could contain something more than the link, like the site title?

Let's start with the copyright info.

I think the empty p could be solved by using the empty css selector, something like this: .site-footer p:empty { display: none; }
This could be added in a css section of the theme.json file

@carolinan @justintadlock I would create a block variation for the policy link. This variation can be addressed within a pre_render_block filter to be only visible if a policy is already published and preventing the empty paragraph as a side effect.

[justintadlock]

@carstingaxion - Yep, that's a solution that I've employed in similar situations. Just not sure if that's something OK to go in a default theme or not, but I'll leave that up to folks to decide.

Let's at least do the copyright. Would be a good use case others can learn from as well (and easy as it doesn't rely on conditionals).

[carolinan]

Part of it is choosing what the bound text should be, in the editor :)

I would also recommend adding a separate pattern or block variation for the copyright section, utilizing block bindings properties. This would allow users to easily insert the copyright element wherever needed.
I just noticed that there's already a pull request for the copyright pattern (#21 ).
