Update README.md (#151)

Move the logo out of the heading to be consistent with other
repositories that have a logo (e.g. https://github.com/bufbuild/buf,
https://github.com/connectrpc/connect-es), and update the README to be
consistent with the language used in [PGV
readme](https://github.com/bufbuild/protoc-gen-validate/blob/main/README.md)
(see also bufbuild/protoc-gen-validate#1012)

 `protovalidate` is a series of libraries designed to validate Protobuf messages at
 runtime based on user-defined validation rules. Powered by Google's Common
 Expression Language ([CEL][cel-spec]), it provides a
 flexible and efficient foundation for defining and evaluating custom validation
 rules. The primary goal of `protovalidate` is to help developers ensure data
 consistency and integrity across the network without requiring generated code.
