Update solidity pragmas

[ChiTimesChi]

Description

This PR aims to use the most recent version of Solidity compiler at the time of opening this PR: 0.8.17.

Previously used version 0.8.13 had a critical bug, described here. One of the side effects present in the test suite was that abi.encode(bytes) would return different values depending on whether the bytes array was in storage or not.
