fix(install): stop libblockdev matching the desktop-environment check (#780)

* fix(install): stop libblockdev matching the desktop-environment check

dpkg -l | grep -E '^ii.*kde' searched the description column too, so
unrelated packages (libblockdev-*) set DESKTOP_DETECTED on Raspberry Pi OS
Lite. Match on the installed package name only, anchored.

* docs(install): correct why the desktop check matched libblockdev

The unanchored .*kde matched the package name mid-word ("bloc-kde-v"),
not only description text.
