Fix CMAKE_DO_NOT_EDIT_HEADER_PREFIX grammar

[will-v-pi]

This change would break all backwards compatibility as that string is searched for to detect a pico-vscode project, and the header is also specified in pico_platform.py so would need to be changed there too. Could you modify this PR to address those concerns?

PR modified as requested.

With this fix I've tested and am happy to merge this PR

Fix applied, thank you.
