[Customs KIT] Docusaurus 3.x upgrade

[ClosedSourcerer]

Customs KIT upgrade preperation

Within this issues all the needed changes for "upgrading" the KIT to fit the requirements with docusaurus 3.X are tracked. The work is down on a seperate branch for each KIT on a specific fork.

To keep the changes small we are working KIT by KIT. For each PR on the fork from branch to main, we will do a official committer review, done by:

• @stephanbcbauer or
• @ClosedSourcerer or
• @matbmoser

For each PR an IP issue should be created. Assumption would be, that we dont need an ip issue for the big bang (merging everything to origin)

Tasks

• create branch on fork

• Migrate KIT (links, sntax) to fit MDX Checker

• API Hub is linked, if needed
