fix(docs): update broken message attachments links to current developer docs URL

[bloodsportshooting]

Summary

Two documentation pages linked to https://docs.mattermost.com/developer/message-attachments.html, which returns 404 — the message attachments reference now lives on the developer portal at https://developers.mattermost.com/integrate/reference/message-attachments/ (the URL already used elsewhere in these docs, e.g. source/end-user-guide/access/client-availability.rst and source/integrations-guide/faq.rst).

Changes

• source/administration-guide/manage/bulk-export-tool.rst: update the message attachments link in the Post object props field description.
• source/administration-guide/onboard/bulk-loading-data.rst: same fix for the bulk-loading Post object table.

Verification

• Confirmed https://docs.mattermost.com/developer/message-attachments.html returns HTTP 404.
• Confirmed the replacement URL returns HTTP 200.
• Scanned all outbound links in the docs source; these were the only two occurrences of this broken link.
