Shortcode add highlight options

[Caesarsage]

Description

Adds an options parameter to the code_sample shortcode and forwards it to Hugo’s highlight function. This enables linenos, hl_lines, and other highlight features when including external files without changing existing calls.

follow-up PR will demonstrate usage #52837

Before:

{{% code_sample file="pods/resource/cpu-request-limit.yaml" %}}

After:

{{% code_sample file="pods/resource/cpu-request-limit.yaml" options="hl_lines=10-14" %}}

Thank you for the PR.

This should be 2 commits and ideally it wouldn't include commit fe845b0.

• add the shortcode (first commit)
• use the shortcode (second commit)

Alternatively, omit the second commit but show reviewers how they can test it out. A follow up PR can set highlighting options for some content.
