HTML visible in the NR install palette list

[Steve-Mcl]

As discussed on Slack:

Sometimes, HTML can make its way through to the NR install palette. Potentionally this may want to be handled in NR code too, but for starters raising here to capture at source.

For reference

• this is the NPM page view (note commented HTML IMG is not shown)
• this is the flows page view (note HTML code shown IMG with closing comment tag)
• this is the markdown for that page

Just to note, npm search results show the raw HTML as the description for that note:

@Steve-Mcl might have a fix: https://github.com/node-red/flow-library/pull/123 (can you test/review?)
