Fixed brew sha256 for v2.5.0.tar.gz

This used to work fine, perhaps something has changed in how Github
creates archives so archive checksum does not match anymore?
Confirmed that actual file content at https://github.com/mvp/uhubctl/archive/v2.5.0.tar.gz
is exactly the same as content for `git checkout v2.5.0`.
Updated checksum to expected value so `brew install uhubctl` should pass.
Closes mvp#489.
