Update Snippets to use the latest version

[ucheNkadiCode]

It would be great if we could create some sort of function call that adds in the latest date of a specific resource. The user should of course have the flexibility to change it to whatever they want afterwards.

Example:
VS Code gives us

resource virtualNetwork 'Microsoft.Network/virtualNetworks@2019-11-01'

but the latest version should be

resource virtualNetwork 'Microsoft.Network/virtualNetworks@2021-03-01'

It would be awesome of we have make this automatic for our resources to have something like resource virtualNetwork 'Microsoft.Network/virtualNetworks@`LatestVersionOfThisResource()' <-- func

I'm assuming that our latest has the most up to date best practices

This seems to be heavily related to #622

Snippets are hand-authored and there is no guarantee that the same snippet code will work with a new API version. The only way to update a snippet to the latest version would be to edit the snippet source code in this repo.

It would also be interesting if we could have a code/action refactoring that could "upgrade" an API version and account for any schema changes between versions. I suspect this would be tricky in practice and there would be a lot of edge cases.
