Pull request overview

This PR updates the EFR32 build Docker image inputs so the Simplicity SDK content needed to build EFR32MG26 targets with LLVM (specifically the Bluetooth link-layer static library) is retained in the image.

Changes:

• Keep the MG26 (xg26) LLVM Bluetooth LE controller liblinklayer.a in the Simplicity SDK keep-list used by the EFR32 Docker image build.
• Bump the base chip-build Docker version stamp to trigger rebuild/publication.
