Added a CLI test for listing resource groups and fixed JSONPath
expressions for the output format.

### Walkthrough
* Correct the JSONPath expressions for the `ResourceGroupResource`
struct in the `table` format options
([link](https://github.com/radius-project/radius/pull/6252/files?diff=unified&w=0#diff-f2e80353ac2e49da41bc04958b9568c662162f7dbb52ada2c328851436925482L81-R85))
* Import the `objectformats` and `to` packages to use the
`GetResourceGroupTableFormat` function and the `to.Ptr` helper function
in the `group list` command test
([link](https://github.com/radius-project/radius/pull/6252/files?diff=unified&w=0#diff-b6f63f3ed2aaeada863bd788b630879282e34fce2ad6672636ea677a37748853L27-R30))
* Create a mock API response with a slice of `ResourceGroupResource`
objects in the `group list` command test
([link](https://github.com/radius-project/radius/pull/6252/files?diff=unified&w=0#diff-b6f63f3ed2aaeada863bd788b630879282e34fce2ad6672636ea677a37748853R107-R118))
* Define the expected output as a slice of `FormattedOutput` objects
with the `table` format and the `GetResourceGroupTableFormat` options in
the `group list` command test
([link](https://github.com/radius-project/radius/pull/6252/files?diff=unified&w=0#diff-b6f63f3ed2aaeada863bd788b630879282e34fce2ad6672636ea677a37748853R130-R138))
* Compare the expected output with the actual output from the
`outputSink` in the `group list` command test
([link](https://github.com/radius-project/radius/pull/6252/files?diff=unified&w=0#diff-b6f63f3ed2aaeada863bd788b630879282e34fce2ad6672636ea677a37748853R130-R138))
