Min/Max constraint should allow decimal for Double types

Overview of the issue

Adding a Max/Min constraint only allows you to set Integers when using JDL, fields such as Double should allow a . in the constraint.

Using the generator prompts works as expected. JDL exported from app that then fails to import:

entity Foo {
  test Double min(0.001)
}

Error message:

If I add quotes around 0.001 it gives a different error

SyntaxError: Error: NoViableAltException: Expecting: one of these possible Token sequences:
  1. [INTEGER]
  2. [NAME]
but found: '"0.001"'

Motivation for or Use Case

You should be able to specify a decimal point in the min/max constraint when supported in the field type.

Reproduce the error

jhipster import-jdl --inline "entity Foo { test Double min(0.001) }"
