Create simple version command

Description

Create simple version command to help with debugging

Motivation

None

Testing

It says "(devel)" beecause it is the version of the locally build command (which has no version). This code should print out the same info as go version -m (binary path)

New command:

 go run ./cmd/pg-schema-diff version                                                                                                   INT х │ 01:01:02
version=(devel)

Example of go version of latest commit sha (it's what's next to the mod). This uses the same go debug info under the hood, so I expect the version command on the installed binary to mirror its output

go version -m $(where pg-schema-diff)                                                                                                ✔ │ 4s │ 01:01:55
/Users/bplunkett/go/bin/pg-schema-diff: go1.22.0
        path    github.com/stripe/pg-schema-diff/cmd/pg-schema-diff
        mod     github.com/stripe/pg-schema-diff        v0.7.1-0.20240909221644-5fe8259b82bd    h1:jF5uaAlsiU0Txzf+7kviuIyqdLcwuAWAJALDH92kXkU=

The command will error if @latest is not provided

Because we don't build the binary in our CI/CD pipeline, this is the best way to retrieve debug information for the binary.
