Highlight `text` code blocks representing command outputs in the docs

[Gedochao]

Describe what needs to be done and why
In our docs we rely on the ChainedSnippets component (defined here) to glue together code blocks showing a command and its output (or connected code blocks in general).
However, it'd improve the readability of our docs if '''bash code blocks had different styling than '''text code blocks (where text is usually used as the tag for outputs).

i.e. looking at the example screenshot, the first line is coming from a bash block, the second is a text block.
we need to make it clear visually, that the latter is the output.
