Shuttle: v0.51.0 update

Axum 0.8 support

Axum 0.8 is now used by default in shuttle-axum.

To keep using Axum 0.7 with Shuttle, use this cargo feature:

axum = "0.7"
shuttle-axum = { version = "0.51.0", default-features = false, features = ["axum-0-7"] }

Support for Axum 0.6 has been dropped with this release.

This feature serves as an alternative to shuttle-persist, which is not supported on shuttle.dev.

Two new output types have been added to #[shuttle_shared_db::Postgres] under the opendal-postgres crate feature:

opendal::Operator, which provides a generic key-value store interface backed by a table in the database.
shuttle_shared_db::SerdeJsonOperator, which provides an interface for storing any serializable type T as JSON in the Operator table. This is similar to the shuttle-persist interface.

Bumped salvo to 0.75 in shuttle-salvo.
Bumped opendal to 0.51 in shuttle-opendal.
Added an optional timeout setting in shuttle-api-client.
Fixed a bug where cargo-shuttle would put gitignore rules on the same line as existing ones.

Refer to the upgrading docs for how to upgrade your projects.
