Important: The page TSconfig directory is now spelled TSconfig 

Description 

The extensions of this set spelled their page TSconfig directory in three different ways — TsConfig, TSconfig and TSConfig. They now all use TSconfig, which is how TYPO3 spells the term and what the core documentation uses.

In this extension the directory was Configuration/TsConfig.

Nothing was broken before, because every import matched the directory it pointed at. The reason to change it is that a filesystem is case sensitive on Linux and case insensitive on macOS and Windows, so a path copied between two of these extensions resolved on one machine and silently not on another — and a page TSconfig @import that does not resolve raises no error, the configuration is simply absent.

Impact 

Every file this extension ships moved with the directory. The imports inside the extension were updated in the same change, so an installation that only installs the extension has nothing to do.

An integrator who references these paths from their own configuration has to update them, because the old path no longer exists:

# before
@import 'EXT:academic_contacts4pages/Configuration/TsConfig/page.tsconfig'
# after
@import 'EXT:academic_contacts4pages/Configuration/TSconfig/page.tsconfig'

Affected Installations 

Every installation that imports a page TSconfig file of this extension by path, or that copied such a path into its own site package. An installation that relies only on the auto-included Configuration/page.tsconfig of the extension, or on its site set, is unaffected.
