[nrf noup] scripts: ci: check_compliance: Exclude some docs

Adds the NCS release notes folder to the exclusion list for
undefined Kconfigs so that old Kconfigs can be used e.g. for old
release notes, and lwm2m carrier library changelog. Also adds a
nrf7x page which details setup instructions for software on Linux
