Fix E2E tests by updating Weight type

[ascjones]

• Updates to use new sp_weights::Weight type for gas_limit.
• Depends on new versions of sp-core etc and subxt

Since the e2e test crate is already using git dependencies and is not currently released to crates.io, I am happy to convert the substrate crate dependencies to git. Once all dependencies are released to crates.io we can use those, and then this crate can be released.

Don't the call sides need to be fixed now that the tests are required to pass Weight instead of u64?

The changes here already change the call argument to Weight?

Was thinking about the actual tests in examples which might pass Weight.

An auto dry run is performed rather than the user supplying it as a parameter https://github.com/paritytech/ink/blob/66c05c9b0a9139990fc2ac8e81090f668ea9e053/crates/e2e/src/client.rs#L574

Nice!

I tested this with the v0.22.1 release of the contracts node and it worked 👍
