You forgot to add an entry in DEVELOPERS file.

There were some coding style issues in this file (indentation, mostly),
reported by "make check-package".

This didn't work: the tarball is named libzenoh-pico-0.10.0-rc.tar.gz,
not zenoh-pico-0.10.0-rc.tar.gz.

The license is actually Apache-2.0 or EPL-2.0

This is not needed, as -DBUILD_EXAMPLES=OFF is always passed when
configuring CMake packages, by the cmake-package infrastructure in
package/pkg-cmake.mk.

This final empty newline was causing another "make check-package"
complaint.

As said above: I fixed those issues, and applied to master. Thanks for
your contribution!
