fix: ensuring the automatic module name is a valid name by replacing the - to . in artifactId

[themaherkhalil]

Currently the jar's automatic module name is invalid as it contains a - in the artifactId. If you run:

➜  0.17.0 jar --describe-module --file mcp-core-0.17.0.jar
Unable to derive module descriptor for: mcp-core-0.17.0.jar
Automatic-Module-Name: io.modelcontextprotocol.sdk.mcp-core: Invalid module name: 'mcp-core' is not a Java identifier

This prevents other projects using modules to import the jar.

The change is to replace the - with a .

After compiling the code to build the jar, running the command will produce:

➜  target git:(main) jar --describe-module --file mcp-core-0.18.0-SNAPSHOT.jar
No module descriptor found. Derived automatic module.
