v2: can't parse numeric value of "maximum" tag

[thokuest]

Describe the bug
Parsing a struct with a float64 field having a floating point minimum/maximum value fails with message:

Error parsing type definition 'CreateInput': can't parse numeric value of "maximum" tag: strconv.Atoi: parsing "0.1": invalid syntax

To Reproduce

type CreateInput struct {
	Factor *float64 `json:"factor" validate:"required" minimum:"0" maximum:"0.1" example:"0.04"`
}

// @Summary      Create Something
// @Accept       json
// @Produce      json
// @Param        Payload   body   CreateInput true "Request Body"
// @Router       /something/create [post]
func Create() {}

Expected behavior
No error is generated and proper OpenAPI v3 model is generated.
