-J exports incorrectly outputs ExifToolVersion as a float

[danielhoherd]

When using exiftool -J the ExifToolVersion value is output as a float, which does not make sense for a version string. The result is that a version like 12.60 is treated as 12.6 which is a significantly different value.

$ exiftool -J -ExifToolVersion test.heic
[{
  "SourceFile": "test.heic",
  "ExifToolVersion": 12.60
}]
$ exiftool -J -ExifToolVersion test.heic | jq .
[
  {
    "SourceFile": "test.heic",
    "ExifToolVersion": 12.6
  }
]

The values output by exiftool are not typed, which leads to problems when converting for the JSON output. If it looks like a number, then ExifTool writes a JSON number, otherwise it quotes it as a string.

@StarGeekSpaceNerd That post seems to describe the problem pretty well. I thought it was just the version string, but it appears to be everything.
