Fixed some Eclipse dependencies version to avoid issues with latest releases

[mrizzi]

The builds are failing from yesterday with the message:

[ERROR] Failed to execute goal on project windup-eclipse-jdt: Could not resolve dependencies for project org.jboss.windup.jdt:windup-eclipse-jdt:jar:5.3.1-SNAPSHOT: Failed to collect dependencies at org.eclipse.jdt:org.eclipse.jdt.core:jar:3.16.0 -> org.eclipse.platform:org.eclipse.core.resources:jar:3.13.200 -> org.eclipse.platform:org.eclipse.core.expressions:jar:3.5.100 -> org.eclipse.platform:org.eclipse.core.runtime:jar:3.12.0 -> org.eclipse.platform:org.eclipse.equinox.preferences:jar:3.10.0 -> org.osgi.service:org.osgi.service.prefs:jar:[1.1.0,1.2.0): No versions available for org.osgi.service:org.osgi.service.prefs:jar:[1.1.0,1.2.0) within specified range

The cause is the latest release (v 3.10.0) published yesterday for org.eclipse.platform:org.eclipse.equinox.preferences [1]: in the pom.xml file it declares this dependency:

<dependency>
  <groupId>org.osgi.service</groupId>
  <artifactId>org.osgi.service.prefs</artifactId>
  <version>[1.1.0,1.2.0)</version>
</dependency>

but this dependency doesn't exist in any public Maven repository (at the comment's date, 2022-06-15).
The "closest" Maven artifact to this one seems to be org.osgi:org.osgi.service.prefs (i.e. without .service in the groupId) which is available, with the expected versions [2].

The solution is all about avoiding org.eclipse.platform:org.eclipse.equinox.preferences:3.10.0 artifact from being used, forcing the previous release (i.e. 3.9.100) to be used instead.

[2] https://repo1.maven.org/maven2/org/osgi/org.osgi.service.prefs/

Commit 6ff860c reverts the changes coming from #1417 because now we're building on JDK 11 so the cause that required those changes (Windup building on JDK 8) is no longer applicable.

Now module windup-eclipse-jdt has these dependencies:

where every Eclipse dependency is inherited but the org.eclipse.platform:org.eclipse.equinox.preferences:3.9.100, required to fix the current build issue.

The issue is still affecting our builds so I'm going to merge to get back to normality for builds ASAP.
