[Bug]: Number example treated as a string when generating swagger file.

[SandorArpa]

Description of the problem/issue

The following mark up
`@SchemaProperty(
name = "price",
schema = @Schema(example = "9090", maximum = "10000000", type = "number", minimum = "1",
description = "Price override for the payment amount. If not present this will defaults to price of product.")) (https://github.com/alphagov/pay-products/blob/529c1873e6ff2e7842a63654aeb50d7d19cb1fda/src/main/java/uk/gov/pay/products/resources/PaymentResource.java#L107)

interpreted as a string in version 2.2.43:

type: number description: Price override for the payment amount. If not present this will defaults to price of product. example: "9090" maximum: 10000000 minimum: 1.

In version 2.2.42 it was interpreted as a number:
type: number description: Price override for the payment amount. If not present this will defaults to price of product. example: 9090 maximum: 10000000 minimum: 1.

Affected Version

2.2.42 to 2.2.43

Steps to Reproduce

Setup a SchemaProperty in a RequestBody where type = "number' and example = "1000"

Expected Behavior

Example is a number, not a string

Actual Behavior

Example is a string

Logs / Stack Traces

N/A

Additional Context

Change did not affect Java classes, eg:

@Schema(example = "1000.00") private final BigDecimal averageAmount;

is still interpreted as a number.

I believe the additional context is not correct, given this example.
(This may be a different cause/area but I would title it exactly the same as this bug so I'll include it here)

comparison between 2.2.43 and 2.2.44 (tested with BigDecimal and Double)
Given this example endpoint and dto:

@PostMapping(path = "/example", consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ExampleDto> crud() {
  return null;
}

private record ExampleDto(
  @Schema(example = "10.00", description = "Bug test decimal value") BigDecimal exampleDec) {
})
