[GOBBLIN-1181] Make parquet-proto compileOnly dependency

[vikrambohra]

Dear Gobblin maintainers,

Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below!

JIRA

• My PR addresses the following Gobblin JIRA issues and references them in the PR title. For example, "[GOBBLIN-XXX] My Gobblin PR"
  • https://issues.apache.org/jira/browse/GOBBLIN-1181

Description

• Here are some details about my PR, including screenshots (if applicable):
  'org.apache.parquet:parquet-protobuf:1.10.1' is not resolvable from MavenCentral because it's missing some of its transitive dependencies. This will cause 'gobblin-apache-parquet' module also not be resolvable from Central (in the future, when it will be published to Central). To fix this, I suggest using 'compileOnly'. This will ensure that 'gobblin-parquet-apache' is cleanly resolvable from Central.

This change unblocks automated consumption of gobblin external artifact at LinkedIn

  Tested by running the build and inspecting the pom files
