🚀 Feature Request: Single Command to Apply Migrations to All D1 Databases in Wrangler

[sugar-cat7]

I'm currently working with multiple D1 databases with the same schema in a Cloudflare Workers project and facing a workflow challenge. My wrangler.toml file defines numerous D1 database bindings, as shown below:

# Example wrangler.toml configuration
[[d1_databases]]
binding = "Test1"
database_name = "test-1"

[[d1_databases]]
binding = "Test2"
database_name = "test-2"

# ... additional configurations ...

Currently, to apply migrations, I need to execute wrangler d1 migrations apply <database_name> individually for each database. This process is manageable but becomes cumbersome, especially when integrated into CI workflows.

A potential command might look like wrangler d1 migrations apply --all, automatically detecting and applying migrations to each database defined in wrangler.toml.
Alternatively, the introduction of a migration group concept could be considered. This would allow defining groups of databases in wrangler.toml that share the same schema, enabling us to apply migrations to all databases in a group with a single command.

This feature would significantly improve the developer experience and efficiency for projects utilizing Cloudflare's D1 databases with Workers.

Agreed, we need to do this.
