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:

proteinfold/tests/colabfold_local.nf.test.snap

Lines 14 to 16 in 668c988

	"colabfold_search": null,
	"alphafold_colabfold": null,
	"mmseqs": null

proteinfold/tests/alphafold2_split.nf.test.snap

Line 14 in 38aff42

"python": null

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.
