doc: add copy about how to curl SHA256.txt

Currently we include instructions on how to check the sha of a downloaded tar-ball, but do not include instruction on how to get the `SHA256.txt` file. This has led to confusion with people thinking that the SHA256.txt is included in that tarball. This commit includes instructions on how to use curl to download the `SHA256.txt` prior to the instructions on how to verify the sha.
