examples/stm32wb: fix linker script.
cortex-m-rt 0.7.2 now enforces the stack is 8-byte aligned. Stack is placed
at `ORIGIN(RAM) + LENGTH(RAM)` by default, which wasn't 8-byte-aligned. See https://github.com/rust-embedded/cortex-m/discussions/469
ST trims 8 bytes from start of RAM, and uses the whole 192kb, so let's just
copy that:
