Important: #88043 - TypeScript sources moved into Build directory

See forge#88043

Description

The TypeScript sources of all system extensions have been moved into the Build directory. The former directory structure typo3/sysext/foobar/Resources/Private/TypeScript has been superseded by the new structure Build/Sources/TypeScript/foobar/Resources/Public/TypeScript.

Note

Mind that Public is now the parent directory of TypeScript.
