docs(release): correct 0.5.0 setup and migration guidance

[hyperb1iss]

The generated 0.5.0 notes contain incorrect upgrade instructions: OpenRGB setup omits enabling the bridge, diagnostics name a nonexistent command, and the display-rotation warning describes a field absent from face requests. Correct those claims, the release archive's udev path, skill compatibility, and the explicit opt-in required to file support requests or resize zones.

The corrections were checked against the CLI, shared API types, SDK client, setup guide, and rig helper, including an independent factual audit. Diff checks pass. The same corrected text will become the public GitHub release body; the existing version tag is preserved.
