:bug: Fix invalid JSON in manifest.json

[adamkirkwood]

Sketchpacks Relay is quite strict on parsing only valid JSON for manifest.json files found within your plugin's repo.

This should fix the following errors as seen on jsonlint.com

Error: Parse error on line 24:
...": [         "Nudged",       ],      "isRoot": true
---------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got ']'

and

Error: Parse error on line 28:
..."isRoot": true   },}
--------------------^
Expecting 'STRING', got '}'

We'll check back on your indexed plugins to see if it successfully re-indexes your plugin with the correct data.
