chore(kno-11112): reference payload size limitation in attachment docs

[scotidodson]

KNO-11112: Docs — update email attachment docs to reference the total payload limit

Summary

• Expands the content property description in the attachment object table to clarify that the 10MB limit applies to the full trigger payload (not per attachment), links to the trigger payload docs, and notes that email providers may enforce stricter limits.
• General cleanup: removed emoji from intro steps, consolidated two **Note** callouts into prose, folded multiple-attachments mention into section intro.

Changes

• content/integrations/email/attachments.mdx — content table row updated with payload limit link and provider limit note; prose and style cleanup throughout

Notes

The 10MB payload limit is documented at send-notifications/triggering-workflows/api.mdx line 64. No changes needed there.

Risk LOW: Clarifies the 10MB trigger payload limit in email attachment docs and performs minor prose cleanup.

Reasons

• Only a single .mdx content file is modified (content/integrations/email/attachments.mdx)
• Small diff: 6 additions and 10 deletions (16 total lines changed)
• No new pages, sidebar changes, component changes, or dependency updates
• Changes are editorial: consolidating notes, updating a table description, and adding a cross-reference link
• Author (scotidodson) is a known repository contributor

Notes

• Verify the cross-reference link to /send-notifications/triggering-workflows/api#trigger-payload resolves correctly on the preview deployment
• The Callout component change (from type="info" + title="Note:" to emoji="💡" + title="Resend inline images.") is a minor style update — confirm it renders as expected
