Update documentation referencing version instead of versionPrefix

[juancarlosjr97]

The documentation currently references version/prefix in places where the correct option is versionPrefix.

Goal

• Update docs to consistently use versionPrefix (instead of prefix) in examples and wording.

Acceptance criteria

• README (and any other docs) examples use versionPrefix.
• Any docs/tests text referring to “prefix” are updated to match the current option name and meaning.
