a11y tests hitting incorrect urls causing timeouts

[nicolethoen]

clean up the list of URLs hit during a11y testing.

• some URLs changed from using demos to patterns so we need to update the regex.
• some demos were moved out of the patterns section to the component sections, but don't have a default 'react' at the end of the URL, hey have 'react-demo' instead.
• some components were deprecated, so they also don't have a default 'react' at the end of the url, they have 'react-demo' instead.
