🩹 [Patch]: Update test to connect a GitHub App using Connect-GitHubApp (#60)

## Description

This pull request updates the `.github/workflows/TestWorkflow.yml` file
to improve the organization and output formatting of GitHub-related logs
in the workflow scripts. The most important changes include switching
from `Format-Table` to `Format-List` for better readability,
restructuring log groups for clarity, and replacing specific
installation token-based connections with a streamlined
`Connect-GitHubApp` command.

### Improvements to output formatting:
* Changed the output formatting from `Format-Table` to `Format-List` for
`Get-GitHubApp` and `Get-GitHubConfig` commands to enhance readability.

### Workflow restructuring:
* Replaced the token-based connection logic
(`New-GitHubAppInstallationAccessToken` and `Connect-GitHub`) with a
simplified `Connect-GitHubApp` command to connect to all installations
of the app.

* Added new log groups for `Contexts` (`Get-GitHubContext
-ListAvailable`) and `GitHubConfig` (`Get-GitHubConfig`) to improve
clarity and organization of workflow logs.
