Add d to the pattern of max_time

[nvnieuwk]

When params.max_time is set to 72.h for example, Nextflow converts that to 3d which doesn't match the current pattern when using the nf-validation plugin.

The following invalid input values have been detected:

* --max_time: string [3d] does not match pattern ^(\d+\.?\s*(s|m|h|day)\s*)+$ (3d)

This PR fixes that issue

Is it okay to merge with that failing test?

Yes for this one, it's on the Nextflow side, and they are already aware of it :)
