Local build generate non consumable pom files

[talatuyarer]

Current main branch build generate having POM containing ${revision} has version.

This is neatly explained in the official maven documentation: https://maven.apache.org/maven-ci-friendly.html#install-deploy I updated main pom with official suggestion. Currently it works on my machine.

should we also add .flattened-pom.xml files to the .gitignore?

[talatuyarer]

We sould not. flatten poms are created under target folder which is on .gitignore : https://github.com/GoogleCloudDataproc/flink-bigquery-connector/blob/main/.gitignore#L1
