Add Snapshot Repository to pom.xml

[marevol]

This issue tracks adding a snapshot repository to the pom.xml file. This change is reflected in the pom.xml, where a new repository section has been added with the URL "https://oss.sonatype.org/content/repositories/snapshots". The snapshot repository is configured to enable snapshots while disabling releases. The workflow files codeql-analysis.yml and maven.yml have been modified to remove steps related to checking out and installing fess-parent. These changes simplify our CI/CD process and ensure better management of our dependencies.
