Ganache: don't confuse network and chain ID

[n4n0b1t3]

Whenever the terms Network ID and Chain ID are used without distinction, it should be noted that both IDs can be different for a server such as Ganache. Thus, in the tutorial at this point here
Solidity, Blockchain, and Smart Contract Course 3:55:09
the network ID and NOT the chain id is copied. As you can see here, my Ganache is using different IDs.

>>> from web3 import Web3
>>> w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:8545"))
>>> w3.eth.chain_id
1337
>>> w3.net.version
'5777'
>>> 

I suggest setting the chain_id programmatically in the source code as follows so that no errors occur.
"chainId": w3.eth.chain_id,

Here is a good article that also says that it is better not to use network_ids.
ChainId vs NetworkId? How do they differ on Ethereum?

And that's why some people are getting different numbers when deploying, you are amazing @n4n0b1t3 !!
Actually, could you make a PR on chronological-issues-from-video.md? this could be very helpful.
