Fix asciidoctor v4 ESM import to unbreak Publish to website

[rrrutledge]

What broke

The Publish to website workflow has failed on every push to main since the asciidoctor dependency was bumped from 3.x to 4.0.2 (Dependabot #628, merged 2026-07-14). The build dies at module load with:

scripts/generate_learning_path_markdown.js:4
import asciidoctor  from 'asciidoctor'
       ^^^^^^^^^^^
SyntaxError: The requested module 'asciidoctor' does not provide an export named 'default'

asciidoctor 4.x is a breaking API change: it dropped the default export and the asciidoctor() factory function in favor of named ESM exports (convert, load, etc.), and convert is now async.

As a result the learning-path content has not republished to innersourcecommons.org for roughly two months.

The fix

• Import the named convert export instead of the removed default factory.
• await the two convert(...) call sites (both already sit inside async callbacks, so no other restructuring is needed).

Why the output is safe

v4's convert produces byte-for-byte identical HTML to v3 on the learning-path articles (verified by converting the same article with both asciidoctor@3.0.4 and asciidoctor@4.0.2 and diffing — no difference), so the generated site content is unchanged. This keeps the Dependabot v4 bump in place rather than reverting it.

Verification

• asciidoctor@4.0.2 resolves the { convert } import and converts on Node 18 (the workflow's runtime).
• Diff of v3 vs v4 conversion output: identical.
• node --check passes on the edited script.
