Fix code blocks

Some code blocks representing console outputs use `bash` while they should really use `console`.
Other misuses are likely to be fixed as well.

Find available lexers at: https://pygments.org/docs/lexers/

Search the repository's documentation for code blocks marked as bash, then compare their contents with the available Pygments lexers. Change console-output blocks to the console lexer and review other likely lexer misuses. Done means the affected blocks use the appropriate lexer consistently.
