Fix Apache Tomcat Importer by not using Semver

[kunalsz]

In reference to the issue #1555

Changes made:

• Usage of Semver versioning is removed which was creating problems
• Only Maven versioning is being used

Apache Tomcat Versioning Overview

Apache Tomcat versions follow a Maven-like versioning scheme, which can include:

• Milestone versions (e.g., 9.0.0.M1)
• Release candidates (e.g., 8.0.0.RC1)
• Regular numeric versions (e.g., 8.5.32)

This is not Semver-compliant, but Maven versioning handles all of these cases

@TG1999 looking forward to your insights !
