Remove empty text element due to errors

[ctbfourone]

Got an error on the last attempted deploy:
[WARN] web-api:WebClient:0 The top-level `text` argument is missing in the request payload for a chat.postMessage call - It's a best practice to always provide a `text` argument when posting a message. The `text` is used in places where the content cannot be rendered such as: system push notifications, assistive technology such as screen readers, etc. [WARN] web-api:WebClient:0 Additionally, the attachment-level `fallback` argument is missing in the request payload for a chat.postMessage call - To avoid this warning, it is recommended to always provide a top-level `text` argument when posting a message. Alternatively, you can provide an attachment-level `fallback` argument, though this is now considered a legacy field (see https://api.slack.com/reference/messaging/attachments#legacy_fields for more details). Error: web-api:WebClient:0 failed to match all allowed schemas [json-pointer:/attachments/0/blocks/1/fields/3] Error: web-api:WebClient:0 must be more than 0 characters [json-pointer:/attachments/0/blocks/1/fields/3/text] Error: Error: An API error occurred: invalid_attachments

The "text": element was empty, so this simply removes it. We can add it back later if it's needed.
