Release notes for STM32CubeIDE v1.2.1

[fronders]

Hello, can you please update the RN0114 document STM32CubeIDE Release Notes with the new info for v1.2.1, as the website contains the v1.2.0 version only

Thanks

We haven't created any release note for that version. It was a minor but necessary bug fix for MP1, nothing else was changed.
