Hostname ends with capital character is not accepted

[ki-ichino-nec]

Package version eg. v8, v9:

v9

Issue, Question or Enhancement:

The validator says the hostname which ends with a capital character is invalid. The regular expression [-Az] in regexes.go may be incorrect.

regexes.go

const (
	// ...
	hostnameRegexStringRFC952        = `^[a-zA-Z][a-zA-Z0-9\-\.]+[a-z-Az0-9]$`    // https://tools.ietf.org/html/rfc952
	hostnameRegexStringRFC1123       = `^[a-zA-Z0-9][a-zA-Z0-9\-\.]+[a-z-Az0-9]$` // accepts hostname starting with a digit https://tools.ietf.org/html/rfc1123
	// ...
)

Code sample, to showcase or reproduce:

validate.Var("aaA", "hostname")

Thanks, I'll take a look when I'm able.

This seems to be fixed with 9dedb06 so it's safe to close this. I can also open a PR for adding a test case for such a case, but it's already covered by "EXAMPLE" test case
