Update subxt requirement from 0.33 to 0.34

[dependabot]

Updates the requirements on subxt to permit the latest version.

Release notes

Sourced from subxt's releases.

v0.34.0

[0.34.0] - 2024-01-23

This release introduces a bunch of features that make subxt easier to use. Let's look at a few of them.

Codegen - Integrating scale-typegen and adding type aliases (#1249)

We rewrote the code generation functionality of subxt and outsourced it to the new scale-typegen crate, which serves a more general purpose.

Since a lot of types used in substrate are rich with generics, this release introduces type aliases into the generated code. A type alias is generated for the arguments/keys or each call, storage entry, and runtime API method (#1249).

Macro - Errors for misspecified type paths (#1339)

The subxt macro provides attributes to specify custom derives, attributes, and type substitutions on a per-type basis. Previously we did not verify that the provided type paths are part of the metadata. This is now fixed: If you provide an invalid type path, the macro will tell you so. It also suggests similar type paths, you might have meant instead.

#[subxt::subxt(
    runtime_metadata_path = "metadata.scale", 
    derive_for_type(path = "Junctions", derive = "Clone")
)]
pub mod polkadot {}

This gives you a compile-time error like this:

Type `Junctions` does not exist at path `Junctions`
A type with the same name is present at:
xcm::v3::junctions::Junctions
xcm::v2::multilocation::Junctions

Macro - Recursive derives and attributes (#1379)

Previously adding derives on a type containing other types was also cumbersome, see this example:

#[subxt::subxt(
    runtime_metadata_path = "metadata.scale",
    derive_for_type(path = "xcm::v2::multilocation::MultiLocation", derive = "Clone"),
    derive_for_type(path = "xcm::v2::multilocation::Junctions", derive = "Clone"),
    derive_for_type(path = "xcm::v2::junction::Junction", derive = "Clone"),
    derive_for_type(path = "xcm::v2::NetworkId", derive = "Clone"),
    derive_for_type(path = "xcm::v2::BodyId", derive = "Clone"),
    derive_for_type(path = "xcm::v2::BodyPart", derive = "Clone"),
    derive_for_type(
</tr></table>
