fix(docs): trigger workflow on README.md changes to keep llms.txt current

[joshuadarron]

Summary

• Replaces the stale nodes/src/nodes/**/doc.md path trigger in docs.yml with nodes/src/nodes/**/README.md — matching what gather.js actually reads.

Problem

gather.js uses NODES_GLOB = 'nodes/src/nodes/*/README.md' (and variant sub-pages at nodes/src/nodes/*/*/README.md) as its source for all node documentation. The doc.md entry in the workflow paths filter never matched any real file, so node doc changes never triggered a docs rebuild — leaving llms.txt and llms-full.txt out of date on the deployed site.

Test plan

• Merge a change that only edits a node README.md (e.g. nodes/src/nodes/webhook/README.md) and confirm the Docs workflow fires.
• After deploy, verify llms-full.txt reflects the updated content.

Closes #1331

📝 Walkthrough

Walkthrough

The docs GitHub Actions workflow trigger path filter is updated by replacing the glob nodes/src/nodes/**/doc.md with nodes/src/nodes/**/README.md, aligning the trigger with the actual filename used by node documentation files. No other workflow logic is changed.

Poem

A bunny hopped through paths one day,
And found doc.md led astray.
"README's the name!" the rabbit cried,
Swapped the glob with one small stride. 🐇
Now docs deploy when READMEs change — hooray!
