fix: Bump hh deploy and solc versions

[idea404]

What 💻

• Bump hardhat zksync deploy and solc versions

Why ✋

• Fetches binaries from GH Releases CDN instead of repositories (related to Headers Timeout Errors found last week)

[idea404]

This PR reintroduces a function that was removed between the hardhat-zksync-solc versions 0.3.15 to 0.4.2, namely this piece of code:

import path from "path";
import { getCompilersDir } from "hardhat/internal/util/global-dir";
export async function getZksolcPath(version: string, salt: string = ""): Promise<string> {
  return path.join(await getCompilersDir(), "zksolc", `zksolc-v${version}${salt ? "-" : ""}${salt}`);
}

Since there is no formatting on scripts or this project level I skipped formatting the file.
