refactor(renderer): metadata tweaks

[0xble]

Link T-3190

Example of updated custom description (default appended description now separated by newlines):

Hey. I'm a placeholder custom description. Just minding my own business.

This membership represents 10% voting power in Party of the Living Dead. Head to https://party.app/party/0x4da6feb8f32416e7ad1e0795742cd64d5b8b8836 to view the Party's latest activity.

Example of metadata when custom banner is set (should always use custom banner if set):

{"name":"CUSTOM_COLLECTION_NAME", "description":"CUSTOM_COLLECTION_DESCRIPTION", "external_url":"CUSTOM_COLLECTION_EXTERNAL_URL", "image":"CUSTOM_IMAGE", "banner":"CUSTOM_BANNER"}

Example of metadata when NO custom banner and custom image is set (should not include banner attribute, blank):

{"name":"CUSTOM_COLLECTION_NAME", "description":"CUSTOM_COLLECTION_DESCRIPTION", "external_url":"CUSTOM_COLLECTION_EXTERNAL_URL", "image":"CUSTOM_IMAGE"}

Example of metadata when NO custom banner and default image is set (should use default Party banner):

{"name":"CUSTOM_COLLECTION_NAME", "description":"CUSTOM_COLLECTION_DESCRIPTION", "external_url":"CUSTOM_COLLECTION_EXTERNAL_URL", "image":"ipfs://QmZKE4XkPvU7Z8CdgK2Cn7gLQ4t8CDkkfnR1j5bZ2AfRJu", "banner":"ipfs://QmTKCqLUQJt3VxGuUqLMj1jcCRRsaZwY4k757Wb7YPzmH2"}
