GetRepositoryResponse is unusable as it does not expose the actual response data

[cguedel]

Elastic.Clients.Elasticsearch version: 8.14.6

Elasticsearch version: 8

.NET runtime version: 8

Operating system version: Win11

Description of the problem including expected versus actual behavior:
Response type GetRepositoryResponse does not expose any useful properties. It's all in BackingDictionary, but this is internal:

Steps to reproduce:

var createRequest = new CreateRepositoryRequest(repoName)
{
    Repository = new SharedFileSystemRepository
    {
        Settings = new SharedFileSystemRepositorySettings
        {
            Location = $"/tmp/{repoName}",
            MaxSnapshotBytesPerSec = new ByteSize("40m"),
            Readonly = true
        }
    }
};

createResponse = await client.Snapshot.CreateRepositoryAsync(createRequest);

// Act
var searchResponse = await client.Snapshot.GetRepositoryAsync(new GetRepositoryRequest($"{repoName}*"));

// Assert
searchResponse.IsValidResponse.Should().BeTrue();
// TODO: assert more properties here

Expected behavior
Expect to get access to the actual response data.

Provide DebugInformation (if relevant):
