Description
When performing Etherscan verification with the Hardhat Upgrades plugin's verify task, verification fails if the proxy contract was deployed from an older version of the Hardhat Upgrades plugin where the proxy contract source code or compiler version was different.
For example, in this thread, an existing ProxyAdmin contract was previously deployed using compiler version 0.8.2 and failed to verify with compiler version 0.8.9.
We should include a repository of proxy contract artifacts from previous versions of the plugins, and attempt to verify against those.

Research direction
Start from the Hardhat Upgrades plugin's verify task and review how it currently verifies proxy contracts. Define how a repository of artifacts from previous plugin versions should be selected and tried, using the older ProxyAdmin compiler example as a case to support. Done means proxies deployed with older source or compiler versions can be verified.
