Runtime Exception - JSON integer is too large or small for an Int64

I'm getting the follwing runtime exception when trying to run the tool against the following two files:
- https://github.com/Azure/azure-rest-api-specs/blob/4ee92e33cbdbec6685e3cfa125a9b80423cac04c/specification/confidentialledger/data-plane/Microsoft.ConfidentialLedger/stable/2022-11-23/confidentialledger.json
- https://github.com/Azure/azure-rest-api-specs/blob/main/specification/confidentialledger/data-plane/Microsoft.ConfidentialLedger/stable/2022-05-13/confidentialledger.json

```

This seems to originate from parsing the maximum int64 `9223372036854775807` [here](https://github.com/Azure/azure-rest-api-specs/blob/1fefe3f5cee88319b17c08a2dbf95e1e983a9f8c/specification/confidentialledger/data-plane/Microsoft.ConfidentialLedger/stable/2022-05-13/confidentialledger.json#L922), which for some reason gets converted to `9223372036854776000` when the tool runs. The value is the same for both specs.

Please also find more details about the error in the CI pipeline: https://github.com/Azure/azure-rest-api-specs/pull/21659/checks?check_run_id=9712102995.

Start with AutoRest.Swagger/PathLevelParameterConverter.cs at line 48, then follow SwaggerParser.Parse and the OpenApiDiff command shown in the report. Reproduce the failure with the linked ConfidentialLedger specifications. Done means the maximum value in parameters.CommitParameter can be processed without the Int64 parsing exception and the comparison completes.
