chore: Relax versions to ^0.8.23 from 0.8.23

[Arvmor]

What?

Set compiler version to be ^0.8.23 instead of 0.8.23
Fixes #88

Why?

When importing the delegation framework into the Foundry project, having a locked compiler version is problematic. The project will not compile if it imports other third-party contracts that use a higher version of Solidity, such as 0.8.27.

For instance, if a project imports both rhineston's module kit and the delegation framework, the project will not compile as most contracts in the module kit use ^0.8.27 and the delegation framework has locked compiler version 0.8.23.
Foundry does not support using multiple compiler versions in the same project.

How?

Allowed using compiler versions 0.8.23 or higher.

Note

Relax Solidity compiler constraint

• Replace pragma solidity 0.8.23; with pragma solidity ^0.8.23; across contracts, enforcers, libraries, interfaces, helpers, scripts, tests, and example snippets
• No functional logic changes; enables building with newer 0.8.x compilers

Currently blocking development on my end, would be helpful to relax these versions reqs
