nf-tests do not capture versions from container contents

[jscgh]

Description of the bug

Versions of container contents are not captured by nf-tests. This occurs for any version information that is retrieved from the software itself (e.g., running a version command inside the container) and not manually set as a variable in the workflow.

Example: https://github.com/nf-core/proteinfold/blob/668c988a275d65e600471d3340dabfe2c28cbe04/tests/colabfold_local.nf.test.snap#L14-L16 https://github.com/nf-core/proteinfold/blob/38aff42d9189fd2863053942005e0fd4eca768c1/tests/alphafold2_split.nf.test.snap#L14

The test profiles use container = 'biocontainers/gawk:5.1.0' instead of the full image, which means the actual version information from the module containers are not captured.
