Add .gitattributes to force `LF` for .sh file line endings - fix devcontainer deployment

[seantleonard]

Purpose

Closes #9 Depending on OS you use and your Git settings, the .sh shell script files for Linux are cloned and given CR LF (Windows) line endings. This caused script execution to fail with error such as syntax error near unexpected token$'\r''` which resulted in the library db failing to deploy and sql tools failing to install.
