doc: harmonize fenced code snippet flags

We had a few code snippets that were using a non-descriptive tag (e.g.
`console` or `text`), whereas the actual language it's using describes
it better, and improves the syntax highlighting. This commit also
removes non-necessary leading chars (e.g. `$`, `>`, or `%`) to make it
easier for readers to copy and paste to try the command themselves.
