Rephrase settings file rename as historical fact (#24580)

## Description

The documentation uses time-relative language ("for Docker Desktop
versions 4.34 and earlier") when mentioning the old `settings.json` file
name, which becomes increasingly stale over time.

This rephrases it as a historical fact: the file was renamed from
`settings.json` to `settings-store.json` in Docker Desktop 4.35.

Fixes #24546
