[Feature]: Output dashboard for the GitHub Action

[Szymon Duchniewicz]

The Pipeline needs a more detailed visible output, with estimated carbon emission values from previous runs. @lydia-rc was originally working on this here. (Waiting for a Draft PR to be opened, will be linked here when it does)

My suggestion (based on discussions from the project group) for the dashboard is:

• Image embedded in a PR comment
• Alternatively (/additionally): GitHub pages deployment of the dashboard?
• Storing data from previous runs in the repository under .github/data folder, as a .csv/.json/.yaml file (discussion on the format tracked here)
• Displaying the data as a barchart comparing previous infrastructures/runs of the pipeline against current
• Display the current deployment as a piechart of different Resources (and/or resource groups?) and their contribution to the carbon footprint
