Hello,

here's the patch that adds 'java-commons-text'. [1]

Unfortunately I had to disable tests as they require JUnit5 (which is
missing from GNU Guix at the moment.)

Also many thanks to Julien Lepiller who helped me to update
'java-commons-lang3' to 3.12.0, which in turn was required to package
'java-commons-text'.
