Problem/Motivation
#2972224: Add .cspell.json to automate spellchecking in Drupal core landed, we can use cspell to check spelling errors now.
As title, this one is to fix "Drupal" related typos.
(This is a novice issue field for @jeffp)
Proposed resolution
- Search "D rural" and replace/correct them with "Drupal"
- Remove the typo "rural" from the dictionary file
