Minor capitalization changes in IDS setup code

[SOM-fermonte]

Describe the bug
There are a few instances of SQL statements that have different capitalization than Database Projects expect in Visual Studio and they generate warnings when building a project. Having the ability to build fresh installs without warnings makes the installation process easier for new adopters.

To Reproduce
Steps to reproduce the behavior:

1. Create a new database instance following the existing instructions.
2. Create a new Database Project in Visual Studio (tested in 2019 and 2022).
3. Import the schema into the project in VS
4. Build the project
5. You can see multiple warnings related to unexpected capitalization

Expected behavior
A fresh install should allow for a simple import and build without errors or warnings.

Screenshots

Desktop (please complete the following information):

• OS: Windows 10 Enterprise
• Visual Studio 2019 or 2022
• Tested on SQL Server 2016/2019 (on-premises) and Azure SQL Server 2019
