ConfigurableActions isVisible condition wrong

Summary

The configurable actions component is meant to be a general purpose component
which can be reused in multiple places.
The appConfig includes multiple switches datasetActionsEnabled, datafilesActionsEnabled, datasetDetailsActionsEnabled and datasetSelectionActionsEnabled.
While currently only datasetActions and datafilesActions are implemented,
the isVisible function of the component depends only on datafilesActionsEnabled,
which means if only datasetActionsEnabled is true, the component is not rendered.
See line 19 in the code:
https://github.com/SciCatProject/frontend/blob/ee7e10808114f7d568d8b7feb244a4423abc5347/src/app/shared/modules/configurable-actions/configurable-actions.component.ts#L19

Steps to Reproduce

set datasetActionsEnabled: true and datafilesActionsEnabled: false in the frontend config

Current Behaviour

the datasetActions component(s) are not rendered

Expected Behaviour

the switch datasetActionsEnabled should enable the component even if datafilesActions are disabled.

Start in src/app/shared/modules/configurable-actions/configurable-actions.component.ts at the isVisible function referenced by the issue. Review how datasetActionsEnabled and datafilesActionsEnabled are read from appConfig, then reproduce the configuration with datasetActionsEnabled true and datafilesActionsEnabled false. Done means the dataset actions component renders in that configuration while the existing datafiles behavior remains correct.
