Tutorial video shows invalid code (lightbulb no longer has `brightness`)

[henrygab]

Describe the bug Users following the tutorial video are instructed to create non-compiling code. This will block users within the target audience.

To Reproduce

1. In browser, load https://github.com/microsoft/devicescript
2. Scroll down to embedded video.
3. Follow along in VSCode with video until ~1m56s, where video instructs to run the program under the debugger.

Expected behavior Example / tutorial code is correct -- it must compile and execute. The importance of having correct sample code cannot be overstated.

Additional context As this is a video, it is not possible to provide a simple PR.

Problematic code:

import * as ds from "@devicescript/core"

const lightbulb = new ds.LightBulb();
setInterval(async() => {
    const brightness = await lightbulb.brightness.read();
    await lightbulb.brightness.write(brightness > 0 ? 0 : 1);
}, 1000) 

Likely correct code:

import * as ds from "@devicescript/core"

const lightbulb = new ds.LightBulb();
setInterval(async() => {
    // intensity is defined as a number between 0 and 0xFFFF
    const intensity = await lightbulb.intensity.read();
    console.log("intensity: ", intensity);
    if (intensity > 0) {
        await lightbulb.off();
    } else {
        await lightbulb.on();
    }
}, 1000)

Thank, video removed until we have the cycles to record it again

[henrygab]

Ok. Will be leaving issue open, as video removal does not appear to have been pushed yet.

Video still appears to show incorrect, non-compiling code, and remains in the readme.
