Add "Insert Resource" to the Bicep.exe file, not just VS code extension

**Is your feature request related to a problem? Please describe.**
The "Insert Resource" command is *excellent* but only works in VS code as a function of the VS Code extension. Please add this to the bicep executable as

````
bicep.exe import "/subscription/.../object/ID"
````

**Describe the solution you'd like**
By adding this feature to the Bicep.exe file, scripting the output of many objects can be simplified.

````
bicep import "id1" >> outfile.bicep
bicep import "id2" >> outfile.bicep
bicep import "id3" >> outfile.bicep
bicep import "id4" >> outfile.bicep
````

`IMPORT` might be the wrong action word for the EXE. We have `build` and `Decompile`, maybe something more like `GET` or `READ`.

Start by comparing the VS Code extension's existing "Insert Resource" command with the bicep.exe command surface, including the existing build and Decompile actions. Define the CLI action and its output behavior, then verify that repeated resource requests can produce usable Bicep suitable for scripting.
