[Feature Request]: Remove console title highlighting

[lcawl]

Prerequisites

• I have searched existing issues to ensure this feature hasn't already been requested
• I have tested using the latest version of docs-builder

What problem are you trying to solve?

The console codeblock support added in #375 "highlights the first line using a new custom highlighter for console code examples where the first line is the HTTP API call".

Per feedback from @drewdaemon, this formatting is unexpected where codeblocks contain multiple API calls.

Proposed Solution

Since we did not have this kind of title highlighting in the old docs (e.g. https://www.elastic.co/guide/en/elasticsearch/reference/8.19/search-your-data.html) I think it's worth considering its removal.

Examples and Research

Per @bmorelli25 "there are 1756 console code blocks in the ES repo. 293 are multi-API snippets".

Alternative Solutions

No response

Additional Context

IMO the more important feature related to Console-specific code blocks that continues to be missing from Docs V3 is #55 / #225

How important is this feature to you?

Nice to have

Is fixing the appearance for multiple API calls also desired? Or do we just want to remove it?

If it's feasible to fix it instead of removing it (even if it's long-term fix, short-term remove), that's fine by me as long as we get some broader input and review before rolling it out.

Similar concerns in https://elastic.slack.com/archives/C07APH4RCDT/p1758015648729739, "...I can see how this rendering makes sense if the snippet was a one-line command typed into a console followed by the output of that command. It might also make sense if the snippet was a single ES request where the first line has the method and path, and the rest is the body, although having the first line only copyable in that case isn't very useful. But it's pretty confusing in this case, where we have two ES requests. It makes it look like lines 2–4 are a group separated from line 1, when in fact it's more like lines 1–2 are one group and lines 3–4 are another. It's a small thing, but it happens quite often in the docs, so it niggles. Is there anything that can be done to improve it? Thanks..."

May be fixed by #1895
