Update build configuration for RAP Runtime 3.22.0 M1

Update build configuration for RAP Runtime 3.22.0 M1

• Use Eclipse Platform 4.25 I20220706-1800 (M1)
• Use Eclipse Orbit 2022-09
• Use Eclipse Jetty 10.0.11

Also removes the version constraint from the import of the Java package
com.ibm.icu.text in the org.eclipse.e4.ui.workbench and
org.eclipse.e4.ui.workbench.swt bundle because there is no bundle
exporting the package with version any more.

Update the lower boundary of javax.servlet package imports in the
org.eclipse.rap.rwt.osgi bundle to at least 4.0.0 in order to ensure
that no lower, incompatible servlet version is imported which leads to
compile errors.

This commit needs a bit more work as it doesn't compile yet... there are some new methods in upstream classes/interfaces:
(Correction: Actually they are not new, they are not yet existent because the build suddenly seems to consume an older version without the new methods.)

I was able to fix the above error by setting the lower boundary of the javax.servlet import to be at least 4.0.0 in our org.eclipse.rap.rwt.osgi bundle. This seems to pass the higher version import to the compiler, and omits the one that doesn't provide the new methods that require implementations/overrides.
