[S02-ethereum/M2-accounts/L2-generating-accounts] Close code html tag to prevent wrong formatting (ln 104)

[diasgab]

Ad you can see in the section https://courses.consensys.net/courses/take/blockchain-developer-bootcamp-registration-2021/multimedia/25085166-generating-ethereum-addresses, the text format is broken in the section "Creating a Digital Signature With Your Key" because there is a missing closing tag for the code block.
