Update Durable Object docs to say that migrations can be inherited in wrangler.toml #15155
Description
Existing documentation URL(s)
https://developers.cloudflare.com/durable-objects/reference/durable-objects-migrations/#durable-object-migrations-in-wranglertoml
https://developers.cloudflare.com/workers/wrangler/configuration/#inheritable-keys
What changes are you suggesting?
We should add the migrations field for Durable Objects to the inheritable fields section of https://developers.cloudflare.com/workers/wrangler/configuration/#inheritable-keys
We should call out in https://developers.cloudflare.com/durable-objects/reference/durable-objects-migrations/#durable-object-migrations-in-wranglertoml that migrations can be overridden in environments.
