Apple Mail incorrectly detected as version 605

[veqryn]

Apple Mail (an email client) uses user agent strings like so:

Apple Mail version 13
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko)

Apple Mail version 12
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/605.1.15 (KHTML, like Gecko)

Apple Mail version 11
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/605.1.15 (KHTML, like Gecko)

Apple Mail version 10
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/603.3.8 (KHTML, like Gecko)

Apple Mail version 9
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/601.7.8 (KHTML, like Gecko)

Apple Mail version 8
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/600.8.9 (KHTML, like Gecko)

It appears that they are tied to the OS version, being "2" less than the OS minor version, though that may or may not be true in the future.

Unfortunately, ua-parser returns the WebKit version (605 major, 1 minor, 15 patch) instead of the version of Apple Mail.
