Jon Robson ba64c4168d Complete transition to Codex color palettes
* Update mediawiki.skin.variables to point non-Codex tokens to
Codex token equivalents
* Replace box-shadow-color-drawer with @box-shadow-color-base
* Leave FIXME comments for migrating the last two CSS variables
* Replace direct access to CSS variable with @color-link-new
design token instead since the former may no longer exist.

/**
* Minerva CSS Custom properties
* ----------------------------
* Please be aware that these properties are accessible via *any* client-side code.
* These variables should mirror Codex design token names and values:
* https://doc.wikimedia.org/codex/latest/design-tokens
* Only include properties that are required for client-side modification.
*
* @private - Currently, these variables are only intended for use by Minerva,
* however, they are designed to mimic the naming convention in Codex tokens
* in order to facilitate an eventual migration to a centralized source.
* @experimental
* @since February 2024 (MediaWiki 1.43)
