fix: Add version for shared assets bundles

[dalkia]

What does this PR change?

• Adds the version to the cacheable url flow of asset bundles
• Adds test to verify that the correct CacheableURL is returned if two scenes request the same AB. If they are equal (or not, depending on versioning) the cache system is LoadSystemBase should return the correct asset accordingly

How to test the changes?

1. Launch the explorer
2. Do the happy path

I still think we keep blocking assets-sharing that could be perfectly shared, but maybe given the current scenario this is the best option?

Currently at least these 2 conditions have to be met for the same asset to be shared between different scenes:

• The scenes have to be using the exact same asset file
• The scenes have to be in the exact same “asset bundles conversion version”, given the assetBundlesBaseUrl.Append(new URLPath($"{version}/{hash}")); (this is something I think will RARELY happen)

We have to take a decision. If two assets have different version, I think that the safer option is not to share them. If the outdated one is broken, the new one may unintentional broken.
