Folder Names Differences Between MSI and Zip

## Question

The 21.0.4+7-LTS .msi installs a folder named "jdk-21.0.4.7-hotspot" but the .zip folder for the same version contains a folder named "jdk-21.0.4+7". This means that we have to rename the .zip folder name to "jdk-21.0.4.7-hotspot" to be consistent. Why are these named different?

For reference, we are using the zip because you can't have the .msi for 21.0.2+13-LTS and 21.0.4+7-LTS installed at the same time.

## Context

Java version:

21.0.4+7-LTS

Your operating system and platform:

Windows 10

Compare the MSI and ZIP packaging entry points for version 21.0.4+7-LTS and trace where each top-level folder name is assigned. Confirm the intended naming convention for both artifacts, then document or test the result so the two package formats produce consistent folder names.
