build(deps): update soroban-sdk requirement from 26.1.0 to 27.0.0 in the soroban group

[dependabot]

Updates the requirements on soroban-sdk to permit the latest version.
Updates soroban-sdk to 27.0.0

Release notes

Sourced from soroban-sdk's releases.

27.0.0

What's Changed

New Features

• CAP-71 — Auth delegation for custom accounts — Adds support for delegating a custom account's __check_auth to another address. CustomAccount::delegate_auth hands authorization to a G- or C-address that performs the actual authentication logic, and CustomAccount::get_delegated_signers returns the delegated signers supplied in the transaction's authorization payload for verification. (#1896)

Improvements

• Zero-copy BytesN::from for [u8; N] — BytesN::from now uses BytesN::to_array instead of allocating, avoiding extra memory allocation and significantly reducing CPU cost on conversions (up to ~80% on larger arrays in end-to-end benchmarks). (#1888)
