Bump version of sqlparser-derive to 0.2.2

[alamb]

As pointed out by @dzil123 #1054 (comment) I apparently did not publish a version of sqlparser-derive that uses the new version of syn:

Just letting you know, the latest version of sqlparser-derive 0.2.1 is still on syn 1.0: https://crates.io/crates/sqlparser_derive/0.2.1/dependencies

So let's bump the version and try to publish again
