Summary
ot-commissioner introduced via PR #43029 for Thread MeshCoP commissioning links against system libevent libraries (libevent_core, libevent_pthreads) on Linux. But docs/guides/BUILDING.md does not list libevent-dev in the “Installing prerequisites on Linux” apt-get command.
This mismatch causes fresh local linux builds of chip-tool / Python controller (and other controller targets) to fail at link time.

Testing
Documentation-only change (no functional code changes). Adding it to the Linux prerequisites aligns local developer setup prerequisites.
