Add devcontainer features (powershell, modules, github cli)

[marko-stanojevic]

Description

This pull request updates the development container configuration and refines dependency management for the project. The main focus is on improving how the dev container sets up user permissions and installs PowerShell dependencies, as well as updating the format and versions of module dependencies.

Dev container improvements:

• Added explicit userGid and userUid settings to the common-utils feature in .devcontainer/devcontainer.json for better control over container user permissions.
• Changed the container setup command from postCreateCommand to onCreateCommand, now using PowerShell's Install-PSResource to install dependencies from requirements.json on container creation, streamlining the setup process.
• Removed commented-out and unused configuration lines for clarity in .devcontainer/devcontainer.json.

Dependency specification updates:

• Reformatted the requirements.psd1 file to use a more structured hashtable format for each dependency, and updated the PSScriptAnalyzer version to 1.24.0 for improved linting and analysis.
