Update README with correct release version

[faisal6621]

I tried the plugin with the given sample configuration:

<plugin>
	<groupId>com.anthemengineering.mojo</groupId>
	<artifactId>infer-maven-plugin</artifactId>
	<version>0.1.0-SNAPSHOT</version>
	<configuration>
		<consoleOut>false</consoleOut>
	</configuration>
	<executions>
		<execution>
			<phase>verify</phase>
			<id>infer</id>
			<goals>
				<goal>infer</goal>
			</goals>
		</execution>
	</executions>
</plugin>

But this worked only when I changed the given version 0.1.0-SNAPSHOT to 0.1.0.
