feat(role): support {pressed: true} for buttons

[jluxenberg]

Hat tip to Sebastian Silbermann for his prior work on PR #692

What: Adds support for querying based on aria-pressed state for elements with a role of "button" (see https://www.w3.org/TR/wai-aria-1.1/#aria-pressed)

Why: aria-checked and aria-selected area already supported; adding the ability to query by aria-pressed should round out support for querying by these types of parameters.

How: This is implemented in exactly the same fashion as Sebastian Silbermann's implementation in PR #692.

Thanks so much for your help! I've added you as a collaborator on the project. Please make sure that you review the other/MAINTAINING.md and CONTRIBUTING.md files (specifically the bit about the commit messages and the git hooks) and familiarize yourself with the code of conduct (we're using the contributor covenant). You might also want to watch the repo to be notified when someone files an issue/PR. Please continue to make PRs as you feel the need (you can make your branches directly on the repo rather than your fork if you want). Thanks! And welcome to the team :)
