VS Extension - update to latest nuget packages

[anthony-c-martin]

I've closed a bunch of PRs that Dependabot raised as they involved lots of dependent assemblies that were not straightforward to fix.

This issue tracks updating all dependencies under the src/vs-bicep folder at once.

Examples of PRs that I closed: #10788, #10789, #10790, #10791, #10792
