Handle error when status runtime information cannot find version in productCollection.

[AraHaan]

Fixes https://github.com/dotnet/sdk/issues/26509.

Changes:

• Change the .First() calls that operate on productCollection to FirstOrDefault() and use nullable annotate the return value to make them nullable.
• Added a new localizable string resource.

Try/Catches obscure the problem - the API in the various BundleIs* calls from the bundle output writer should be changed to return a nullable bool instead so that we can accurately detect the non-existence of the requested runtime in the ProductCollection. Then for those 'not found' cases we can use the message you've provided.

Alright, about to switch it to using the nullable bools option instead of try/catch. Although I am not sure how to fix the false compile errors with it thinking that the translation files need to be updated (as I updated them manually).

If anyone could help fix that, I would be ok with it.

Edit: I have no squashed the commits into a single commit. I also think that now the only thing that needs to be done are the translations that gets run (I think) by the CI after merge.

Hopefully I finally fixed the nullable issues.

I think the current failures is unrelated.

Is this planned to be merged soon before 7.0.100 stable is released to the public?

Thank you for your contribution. Retargeted to the 7.0.1xx branch and set to automerge. This will be included in 7.0.1xx-rc2.

When can we see this in the daily builds of the rc.2 sdks? Currently I do not see it in the one listed under dotnet/installer to try it out locally from there.
