`peripheral.find` should return varargs, not an array

As per the official documentation:

Returns

table... 0 or more wrapped peripherals matching the given filters.

Given a Lua script for CC: Tweaked:

local n_monitors = select('#', peripheral.find("monitor"))
print(n_monitors)

... with no monitors connected, the script prints 0, with one monitor, the script prints 1, and with two monitors, the script prints 2. So, the function returns varargs.
