Email input: Update the typeMismatch error message

[radmorecameron]

"Use a standard format" could cause added confusion

I believe it should be updated to: Enter a valid email address to continue. Example: [email protected]. instead of Enter a valid email address to continue. Use a standard format. Example: [email protected].

For French, it just says "enter your email" and not "enter a valid email" so I think that should be updated to be consistent with the english translation.
