Add Email bean validation annotation for "format":"email"

[joelittlejohn]

Things to consider if are using the includeJsr303Annotations feature:

• If you have useJakartaValidation turned on, you'll now see jakarta.validation.constraints.Email added to a property when using "format":"email".
• If don't have useJakartaValidation turned on, you'll now see javax.validation.constraints.Email added to a property when using "format":"email".
  • The Email annotation is introduced in the bean validation spec 2.0, so you will need to upgrade to javax.validation:validation-api 2.x (2.0.1.Final is a good choice). Note, all old annoations are maintained (with the same fully-qualified name) so upgrading this should not break anything.
  • If email validation is still not happening, your validator might only be doing bean validation 1.0 or 1.1 validations. You would then need to upgrade your validator (e.g. with bval, upgrade to 2.0.5 or later).

If you receive compilation errors because javax.validation.constraints.Email cannot be found, upgrade to javax.validation/validation-api 2.0.1.Final.

If you receive compilation errors because javax.validation.constraints.Email cannot be found, upgrade to javax.validation/validation-api 2.0.1.Final.

Note that given annotation can't be used when targetVersion is less that 1.8 as it has:

• @Retention(RUNTIME)
• @Target contains TYPE_USE which is available since 1.8

Those who target older version might also need to make sure that version of javax.validation/validation-api being used is compatible with targetVersion

Nice work!
