Remove Java 8 from GitHub workflow (ECJ needs Java 11+)
Since JDT Core 3.27 (Java 17) and Eclipse 2021-09 (4.21), respectively,
ECJ no longer works on JDK 8. Even if we backport JDT Core classes, some
of its dependencies contain Java 11 class files, which ultimately also
means that ACJ no longer works below JDK 11 due to those transitive
dependencies, e.g. org.eclipse.core.resources-3.14.0.jar.
For now, I added JDK 14 to the build matrix, i.e. we currently have 11,
14, 17. When JDK 18 is released, we can switch to 11, 17, 18, i.e. keep
the two LTS releases plus the latest one.

Switch from 'libx' to 'lib', delete all obsolete binaries
Because 'cd lib && mvn compile' can now download and (un)zip many
previously SCM-committed third-party dependencies, the following 'lib'
subdirectories have been deleted:
- ant
- asm
- commons
- jarjar
- junit
- regexp
- saxon
This one is new (but not stored in SCM):
- jdtcore-aj
For each of them, there now is a .gitignore entry, so as to prevent
developers from accidentally committing the downloaded binaries again.

Use special Maven settings with access token to GitHub Packages
The access token is for the 'kriegaex' account. Can be adjusted or
extended in order to support other Package registries, too. for now, I
just want to see it this solves the authentication error problems during
GitHub CI builds.
The new file .mvn/settings-read-github-packages.xml contains additional
information and links to online sources, explaining why this is
necessary.

Enable CI build to be run manually and add download libs step
Via 'workflow_dispatch' users with the necessary access rights can now
run the GitHub Actions workflow from the web UI.
Still in testing stage in redundant module 'libx', prepare for the
future situation that currently committed binaries in 'lib' shall be
replaced by downloaded ones.

Try to avoid 'HeadlessException: No X11 DISPLAY' on GitHub Actions
We have 84 times this kind of exceptions in 'ajde' tests in our build
logs on GitHub, even though the tests seem to pass:
HeadlessException: No X11 DISPLAY variable was set,
but this program performed an operation which requires it.
I found this discussion:
https://github.com/juliangruber/browser-run/issues/147
And then this GitHub Action:
