test: modernize pdfbox test (rockcrafters#420)

* test: use Ubuntu base image only

Use the same Ubuntu base image to provide shell to avoid binary
incompatibility.

* test: modernize pdfbox example

Bump version to 3.0.3 and use the release chisel.
Note: had to add workaround due the missing CA certificate:
