Improve spellcheck

[stevepiercy]

It would be good to improve spellcheck and consistency of spellings. For example:

JavaScript, instead of javascript / Javascript / js
Node.js, instead of nodejs / NodeJS / node

Use caution when doing global find and replaces to not overwrite commands or code blocks that use those strings.

To improve spellcheck, add words to:

• styles/config/vocabularies/Plone/accept.txt
• styles/config/vocabularies/Plone/reject.txt

Note that when you add a correct spelling in accept.txt, then you do not need to add incorrect casings of the same term to reject.txt. See https://vale.sh/docs/keys/vocab#case-sensitivity.
