[GHF] Remove app { name databaseId} query (#160494)

From `PRCheckSuites` fragment, as it's causes security exception when used with new GITHUB_TOKEN, that will looks as follows
```
RuntimeError: GraphQL query

, args {'name': 'pytorch', 'owner': 'pytorch', 'number': 159820} failed: [{'type': 'FORBIDDEN', 'path': ['repository', 'pullRequest', 'commits', 'nodes', 0, 'commit', 'checkSuites', 'edges', 4, 'node', 'app'], 'extensions': {'saml_failure': False}, 'locations': [{'line': 26, 'column': 7}], 'message': 'Resource not accessible by integration'}]
```
But the same query works fine if executed using one's Personal Access Token

Updated mocks file by running
```
sed -i -e s/a32a7ca3a2f6e2c9de07aef821b0111539758b4ac254f8a3432af32314f94876/8e262b0495bd934d39dda198d4c09144311c5ddd6cca6a227194bd48dbfe7201/ gql_mocks.json
