Minimal steps to reproduce

Hi guys I have a found a typo in your webpack configuration that is blocking the app from runing:

communication-services-javascript-quickstarts/add-1-on-1-video-calling/webpack.config.js

Line 19 in 60245b4

'./index.thml',

Any log messages given by the failure

Webpack error when tyrint to run the app

ERROR in unable to locate 'communication-services-javascript-quickstarts/add-1-on-1-video-calling/index.thml' glob

Expected/desired behavior

Expect to run the app successfully.

This typo is also in /add-1-on-1-video-calling/webpack.config.js

Code says:
},
plugins: [
new CopyPlugin({
patterns: [
'./index.thml',
'./styles.css'
]
}),
]
};

when it should say:
},
plugins: [
new CopyPlugin({
patterns: [
'./index.html',
'./styles.css'
]
}),
]
};
