Bug 582078- Cannot install via Oomph due to EclEmma update site

This commit solves the existing problems while installing via Oomph:

- The Mylyn EGit connector feature has been renamed and the Mylyn
repository URL has been updated.
- The EclEmma repository URL has been updated.
- FindBugs has been replaced with SpotBugs, as the former is not Java9+
compatible.

Bug 582227- Feature SWTBot JUnit5 Support fails to install

Beginning with 2022_09, these bundles are no longer available in a
standard Eclipse installation:

- org.junit.platform.commons
- org.junit.platform.engine
- org.junit.platform.launcher

Replacing them with their newer MavenCentral
equivalents would break compatibility with older Eclipse versions (those
earlier than 2022_09):

- junit-platform-commons
- junit-platform-launcher
- junit-platform-engine

Therefore, this patch removes them altogether, as the needed
dependencies are also set in the bundle manifest using a Import-Package
directive.
