Move relevant `sh` codeblocks to `console`

[mkatychev]

yeah so my stance on that is that writing into a console is not normally syntax highlighted either, so it matches.

If we have a shell script, or a bash script, then it makes sense to use those, but my stance here is that if it's a console command you're supposed to enter there are other ways to make it more readable:

something \
    --like this \
    --rather-than console

and if it's code, then it should be highlighted.
