Handle input not enclosed in quotes in "Deploy to AKS" and "Deploy to EKS" actions

[mvlassis]

Closes #1034

This PR updates the deploy-to-aks.yaml and deploy-to-eks.yaml scripts to be able to handle values not enclosed in quotes. This is achieved by adding a preprocess-input job that processes the input to add quote characters and create a valid JSON array. An example of a valid input is:

1.8,1.9,latest

Additionally, the preprocess-input job removes space characters, this means that input like this is also handled properly:

1.8, 1.9, latest

Nice to see this worked on @mvlassis!

With a quick glance we should improve the following:

1. The script is duplicated in the 2 different actions
2. It's using bash that make it a bit hard to read

To mitigate the above I suggest we create a new script under scripts/gh-actions/pasre_versions.py and use this common script for both places (open to suggestions on the folder structure of course)

[mvlassis]

@kimwnasptd Totally agreed! Also, peeking at the 2 actions, there is a lot of overlap which can potentially be condensed. Should we create a task for merging all the logic into a new Python script under scrtips that will contain this logic into separate functions?

I'd say it's OK for now, we'll either way start relying less and less on these actions once SolQA picks up testing.

So no need to focus more time on these I would propose
