Documentation: Missing `cd` in STM32 Build Instructions

[c-alpha]

This set of STM32 build instructions

AtomVM/doc/src/build-instructions.md

Lines 762 to 767 in 0f4a060

	```shell
	$ mkdir build
	$ cd build
	$ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/arm-toolchain.cmake ..
	$ make
	```

seems to be missing a

$ cd src/platforms/stm32

at the start (i.e. insert as a new line after 762)?

Thank you for opening this issue. We do want to make sure the documentation is clear and easy to follow. I guess it should have been more explicit, but the step above does say starting “from inside the AtomVM/src/platforms/stm32 directory:”

While that is certainly the case, the examples for all other platforms in this file do include the cd command.

Hence, in the spirit of "mixed style is worse than bad style", I would welcome either removing the cd commands from all other examples, or adding the cd command in this single case.
