Translator Wrapper defaults to `us-east-1` for SAR applications

This seems to be the same issue reported in #2065 and fixed in v1.27.2, as per comment https://github.com/aws/aws-sam-cli/issues/2065#issuecomment-886450375

However, we are seeing something very similar with the latest version v1.40.1.

### Description:

`sam package` doesn't seem to replace the region when using `FindInMap` to specify the `ApplicationId` of a SAR Application.

### Steps to reproduce:
Using a template like this:
```
Mappings:
ApplicationRegionMap:
eu-west-1:
apparn: arn:aws:serverlessrepo:eu-west-1:123456789012:applications/your-runner-application
us-east-1:
apparn: arn:aws:serverlessrepo:us-east-1:123456789012:applications/your-runner-application
us-west-2:
apparn: arn:aws:serverlessrepo:us-west-2:123456789012:applications/your-runner-application

Resources:
YourSARApp:
Type: AWS::Serverless::Application
Properties:
Location:
ApplicationId:
!FindInMap [ApplicationRegionMap, !Ref "AWS::Region", apparn]
SemanticVersion: 0.0.1
```

Run `sam package`:
```
- sam package
--template "your-template.yaml"
--s3-bucket "${S3_BUCKET}"
--s3-prefix "My-Artifacts"
--output-template-file "mock-template-export.yaml"
```

### Observed result:
When running this command in `us-west-2`, the command fails:
```

```
because it's trying to create the resource using the app in `us-east-1`, which is not the region where this instance of CodeBuild is running.

### Expected result:
When running in a region different from `us-east-1`, I would expect the translator wrapper to resolve the region correctly. I would expect my command to try to use the app in `us-west-2`,

### Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: `aws/codebuild/amazonlinux2-x86_64-standard:3.0`
2. `sam --version`: 1.40.1
3. AWS region: us-west-2

Let me know if you need any further details.

Thanks!
