Non-informative message for file-path format that should be file-path-pattern

[toniher]

I was unable to validate a parameter that was denied as file-path and should be file-path-pattern instead. Example that needed to be changed:

        "genomes": {
          "type": "string",
          "description": "Path to fasta genome files",
          "format": "file-path",
          "default": "./test/GENOMES/*_gDNA-subsetted.fasta.gz"
        },
