I think we should add VSCodium to the table of tools in LICENSE.asciidoc as it has a different license (see https://github.com/VSCodium/vscodium/blob/master/LICENSE).

Also we need to add the tool to both Help.properties and Help_de.properties

I would suggest moving vscodium to a seperate folder and not puting it together with vscode to improve readability but its not a must. Maybe @hohwille can suggest if this is needed here or not. Otherwise, everything is fine from my point of view.
Nice job @laert-ll

Also i think we are missing tests for the VSCodium. Maybe something like https://github.com/devonfw/IDEasy/blob/main/cli/src/test/java/com/devonfw/tools/ide/tool/vscode/VscodeTest.java
