[BUG] ignore_malformed doesn't work for scaled_float

Describe the bug When index has mapped field of type scaled_float with ignore_malformed set, and a document is inserted with value of this field equal to false, then mapper_parsing_exception is thrown.

Interestingly, this bug isn't reproduced for a regular float fields.

To Reproduce Steps to reproduce the behavior:

Create an index

PUT {{ENDPOINT}}/test { "mappings": { "properties": { "amount": { "type": "scaled_float", "ignore_malformed": true, "scaling_factor": 100.0 } } }, "settings": { "index.mapping.ignore_malformed": "true" } }
Try to insert document

POST {{ENDPOINT}}/test/_doc { "amount": false }
See error

{ "error": { "root_cause": [ { "type": "mapper_parsing_exception", "reason": "failed to parse field [amount] of type [scaledfloat] in document with id 'iL1EJ4ABZDKYwbEvExL'. Preview of field's value: 'false'" } ], "type": "mapper_parsing_exception", "reason": "failed to parse field [amount] of type [scaledfloat] in document with id 'iL1EJ4ABZDKYwbEvExL'. Preview of field's value: 'false'", "caused_by": { "type": "json_parse_exception", "reason": "Current token (VALUE_FALSE) not numeric, can not use numeric value accessors\n at [Source: (byte[])\"{\n \"amount\": false\n}\"; line: 2, column: 20]" } }, "status": 400 }

Expected behavior
