documentation Add "Latest updates" page

Adds a latest updates page with some initial content. Closes #1301.

I've prioritised news that requires user action (i.e. deprecations), but open to other ideas too.

Also worth noting that we already have https://docs.quantum.ibm.com/announcements; maybe we should link out to that from the sidebar and more actively publish news there?

thanks Frank!

I see all these latest updates are hardcoded into the page, can you think of any ways to make this more automated? I like the idea of summarising some of the biggest things that have happened recently with code examples but I think its going to be difficult to maintain. If we cant think of a more automated way to generate this page then I think we should stick with the type of thing you did in the first paragraph - just listing out links of where people can find latest updates.

Some extra things we could link out to:

product announcements page
latest Qiskit release blog (this might be something we need to manually update)
maybe the events page? for news about latest events coming up: https://www.ibm.com/quantum/community#events

Also I think it would be good to split sections out by package - so have a section at the top which is for general updates (e.g. link to product announcements, qiskit blog etc.) then a section of Qiskit SDK (link to release notes and latest release blog), then runtime, then transpiler service, then maybe a community section (with the events link?)
