docs: update keywords.json

Related Issue: https://github.com/ArcGIS/icon-explorer/issues/6

Summary

Updated the keywords.json file by merging codepoint values from fantasticonrc.json.
Each icon entry now includes a new "codepoint" field, populated from the codepoints list or set to an empty string if missing.
This is in the hope that we can update the reference page to Supports improved search and integration for the icon font, enabling codepoint-based lookups based on keywords.

Can you revert the changes to the lockfile?

Can you revert the changes to the lockfile?

Sure — just a heads-up: that change happened automatically when I ran the launch command, which we do for every icon release. If I revert it now, it’ll likely reappear with the next icon release.
Is there a specific issue you’re seeing occur with it?

It looks like launch runs npm install, which can update the lockfile depending on the machine, but those changes shouldn’t be included when updating keywords.json as they are not related.
