Ignore leading zero on Australian phone numbers

[authentified-dave]

Hello Team Clerk,

This is a minor UX niggle.

In Australia, our mobile numbers start with 0 and have the format 0XXX XXX XXX. When using this format on other services that have mobile phone number inputs with a region selector, they tend to either ignore/forgive/or strip silently the leading zero.

Clerk however throws an error.

Most Australians are used to typing their full number / not used to using international prefixes (but that's changing)
