Outdated/vulnerable dependencies

java-rdfa has not seen a new release since 11 years. It has outdated dependencies that make it difficult to incorporate the library in projects due to version conflicts.

Additionally there are security vulnerabilities in dependencies (e.g. CVE-2021-39239) that have been fixed in newer versions.

Please update the dependencies to their current versions and release an updated version of java-rdfa that contains these updated dependencies to Maven.
