DOC: error in CI log messages

### deployment template

None

### Bug description

In the CI, it seems that something is wrong with the way `pypandoc-binary` allows us to leverage `pandoc`.
Some verifications must be performed in order to be sure that we can use `pandoc` binary through `pypandoc-binary` installation.


### Expected Behavior

_No response_

### Steps to reproduce

_No response_

### Relevant log output

_No response_

Start by reviewing the CI deployment template and the installation path involving `pypandoc-binary` and `pandoc`; the issue provides no file or test location, so first reproduce the CI behavior and inspect its logs. Done means the required verification succeeds and the CI log messages accurately report whether the `pandoc` binary is usable.
