maven/trivial-test: Update pom.xml to use https (added note in README.txt) for 2.5.0-rc-20230521v2.5.0

Note: Maven version is 2.5.0-rc-20230521,
but jar manifest version is 2.5.0-rc-20230520 due to 'day-leap'.
Compare git-sha1 .. all good ;-)

Refined README.txt

TestJOGL prints the build-in manifest version of the jars.

 It should download all of the required packages (which may be quite a few

 program.
 
+The '-U' option somewhat was required to force an update.
