Soroban storage types conflict with named return parameters in open zeppelin.

[GeorgiosDelkos]

Describe the bug
Version 0.3.4 added support for Soroban storage types: persistent, temporary, instance.
Openzeppelin contains a contract implementation that has a function with a return parameter named instance.
Due to the newly added Soroban storage types this can no longer be parsed.

To Reproduce
Steps to reproduce the behavior:

1. Ethereum
2. https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/proxy/Clones.sol#L28
3. 0.3.4 and up
4. Parsing error
5. No parsing error

Expected behaviour
The file should parse correctly without an error.
Consider adding these behind a feature gate.
