Cannot add other yaml files that are not source file in `queries` directory

[zeyarpaing]

Since source file contains credentials, I've added to .gitignore and want to provide an example file in the same directory for fellow teammates. Currently it uses example yml/yaml file as source file and resulting in authorization issues with DB provider. Spent a lot of time for debugging this and found this part of code in source_manager package.

Steps To Reproduce

• Created a source.example.yml for example source file with dummy values
• Run latitude run or latitude dev
• Got unauthenticated error (using bigquery connector)

Environment

• Node version (v20.12.2):
• npm version (10.5.0):
• Latitude CLI version (1.10.6):
• Latitude project version (2.0.5):
• OS: macOS 15.0.1 (24A348)
• Browser: Chromium
• Database: BigQuery

Expected Behavior

Should search and parse source.yml or source.yaml as source file.

Actual Behaviour

Searches for any files with yml or yaml extensions and using the first one that is found.
