feat: replace console banner with relationships GA announcement

[atharvadeosthale]

Summary

• Replace the Terraform provider promo with a "Database relationships are out of beta" announcement linking to the GA blog post.
• Swap promo asset (relationships-out-of-beta.png derived from the blog cover) and drop the now-unused terraform-provider.png.

Test plan

• Run console with PUBLIC_CONSOLE_MODE=cloud, confirm the bottom-left banner renders with the new copy and image.
• CTA "Read announcement" opens https://appwrite.io/blog/post/relationships-are-out-of-beta in a new tab.
• Dismiss persists (new id modal:relationships_out_of_beta_announcement so prior Terraform dismissals do not carry over).

Greptile Summary

This PR swaps the bottom-left console banner from the Terraform provider promotion to a "Database relationships are out of beta" announcement.

• bottomAlerts.ts: All fields are updated — new promo id (modal:relationships_out_of_beta_announcement), new title/message copy, and a new CTA link pointing to the GA blog post. The new id correctly ensures prior Terraform dismissals do not suppress this banner.
• Images: relationships-out-of-beta.png is added and terraform-provider.png is deleted; the same image is used for both dark and light themes (consistent with the previous Terraform banner's behavior).

Confidence Score: 5/5

This is a straightforward content swap with no logic changes — safe to merge.

The change touches only copy, a new image asset, and a modal id. All fields are consistent with the previous promo object, the old image is properly cleaned up, and the new promo id correctly breaks any prior dismissal state from the Terraform banner.

No files require special attention.
