Add an accordion (or FAQ) block

[ninetyninew]

Describe the solution you'd like
Add an accordion style block to allow text to be clicked to reveal content - like an FAQ.

Example functionality: https://www.w3schools.com/howto/howto_js_accordion.asp

Describe alternatives you've considered
FAQ block plugins exist to do this but this form of functionality is something which could be used on a wide variety of websites or multiple purposes - not just for FAQs.
