Description of the bug

The prokka module in nf-core/modules is using a Conda environment specification that allows GNU Parallel to update to version 20260422 (latest), which causes failures when processing certain annotations. This issue specifically occurs when Conda-based CI tests are launched.

The problem has been identified and fixed in the nf-core/bacass pipeline (PR #303) by pinning GNU Parallel to version 20241122 (conda-forge::parallel=20241122), matching the version used in the Docker/Wave container.
