📄 Add dependency checking instructions to README

This commit introduces instructions on how to verify the installation of
the PSSQLite module, a dependency of our project.

The changes include:

- A new step in the Installation section of the README.md file that
  instructs users on how to check if the PSSQLite module is installed.
- Detailed explanation of the command `Get-Module -ListAvailable -Name
  PSSQLite` and its output.
- Instructions on how to install the PSSQLite module if it is
  not already installed.

These changes aim to provide clear guidance to users on how to ensure
that all necessary dependencies are correctly installed. This will help
users to set up the project correctly and avoid potential runtime
errors due to missing dependencies.
