fix: Require web3>=7.0.0 to avoid breaking API changes

[eureka-cpu]

Fixes a bug that some users were facing that was pulling in an outdated version of the web3 library that uses different naming conventions than the exposed API from the SDK.

@r-vdp I was running into some issues with uv sync. I'm not well versed with python dependency management, so unsure if it's just a skill issue on my part or if there's a problem with the build env:

$ uv sync
Resolved 69 packages in 0.79ms
  × Failed to build `golem-base-sdk @ file:///home/eureka/Code/golem-base/python-sdk`
  ├─▶ The build backend returned an error
  ╰─▶ Call to `flit_core.buildapi.build_editable` failed (exit status: 1)

      [stderr]
      Traceback (most recent call last):
        File "<string>", line 8, in <module>
      ModuleNotFoundError: No module named 'flit_core'

      hint: This usually indicates a problem with the package or the build environment.

What python version are you using? Maybe we need to relax the version bound for flit_core in pyproject.toml to match the minimal python version that we require.

Just whichever version comes with the devShell
