Fix cspell (ignored words, and ddev compatibility)

Problem/Motivation

Two things:

1. Merge Requests in SVG Image Field's issue queue are failing automated tests, due to the `cspell` step, caused by the site studio submodule using the British "colour".

Error message:

$ echo "Executing $CI_PROJECT_DIR/$_WEB_ROOT/core/node_modules/.bin/cspell -c .cspell.json --show-suggestions --show-context $CSPELL_PROGRESS $_CSPELL_EXTRA ."

2. using `ddev cspell` is broken when using Drupal 11.2 or higher.

It looks like by default, yarn install, now uses plug-n-play which no longer installs the "cspell" binary into web/core/node_modules/.bin/

Steps to reproduce

Proposed resolution

1. Add "colour" to our .cspell-project-words.txt file, Since we have zero control over Site Studio's internal naming schemes.

2. Fix .ddev/commands/web/cspell to detect binary executable location (be that via the newer Yarn PnP location, or the old node_modules/.bin/ folder location.
