[Cherrypick] [Port] Modified capitalization in metadata queries (#2315)

## Port metadata

- Porting from `main` to `release/1.2`
  - Issue: #1896 
  - PR: #1921

## Why make this change?

- Resolves #1896

## What is this change?

- These changes impact API builder startup. The query output has not
been modified, but certain field references are capitalized.
- The proper case is used to avoid "field not found" and "key field not
found" errors when the database collation is case-sensitive.

## How was this tested?

- [x] Integration Tests - Ran locally; about 5 tests failed, but it was
the same ones that failed before modifications
- [ ] Unit Tests

## Sample Request(s)
- N/A
