[thomasfroehle]

Why make this change?

• Fixes [Bug]: Quoted Table name are not supported #2385

What is this change?

• In SqlMetadataProvider.PopulateColumnDefinitionsWithReadOnlyFlag the QuoteIdentifier-method of the SqlQueryBuilder was not used to add quotes to the table name

How was this tested?

• Integration Tests -> I'm happy to extend the integration tests, if this fix seems like a good idea
• Unit Tests
• manually

Sample Request(s)

Sample configuraiton:

"MyTable": {
  "source": {
    "object": "schema.\"MyTable\"",
    "type": "table"
  }
}

Looks good, consider adding tests either in this or follow up PR if this is getting stale.
