Description

I'm the type of person that prefers to use keyboard shortcuts and naviation as much as possible. It's become extremely common to have Ctrl+K initiate a search in library documentation. Some examples: ESLint, React, Prettier. I don't know them by name but I'd assume most "doc generation" libraries offer this option at this point.

This PR adds this shortcut as an option to our own docs.
It also opens the first "result"/item in the sidebar when hitting enter while the class filter is focused.

These two small changes make it sooo much nicer to quickly jump around different pages of docs if you know the name. There's likely many other changes we could do to improve our documentation (like searching properties??) but this seemed like a very small but quick win.

No issue

Testing plan

• run npm run build-docs
• npm start and open the docs page locally
• Hit Ctrl+k and make sure it focuses the search on the home page and class pages
• Hit enter and make sure it opens the first result
• Make sure the new keyboard shortcut indicators show up nicely on all pages.
