Issue description

I started to see this error in our production build when updating from v2.47.0 to v2.61.0 (since also tried v2.62.0)

Serverless Error ----------------------------------------

 An error occurred: ApiGatewayBcbserverapiRequestValidator - Resource handler returned message: "Request Validator name must be unique (Service: ApiGateway, Status Code: 400, Request ID: 30e29e25-296a-42c0-8e6d-cc8a6f31b826, Extended Request ID: null)" (RequestToken: f3479759-3512-b778-ed37-ea6faf4034d5, HandlerErrorCode: AlreadyExists).

Somehow it tries to create a RequestValidator that already exists. I can get the deploy to work when I rename the validator just before I deploy using aws apigateway update-request-validator --rest-api-id {apiID} --request-validator-id {validatorId} --patch-operations op=replace,path=/name,value=some-other-name

Is there a way to turn off the request validators? I don't really need those and have no idea why they're turned on here but not on some of my other APIs
