Accessing a dict/list variable with &/@ is not recognized in autocompletion

[Chris-Schr]

Describe the bug
When I create a dict &{variable} or a list @{variable} and want to access it with ${variable} it is not recognized in autocompletion.
I also does not find the variable when holding ctrl+click.

To Reproduce
example code:
*** Variables ***
&{test} fdj=dfk dfkj=dkf

*** Test Cases ***
Test
Log to Console ${test}

Expected behavior
Autocompletion should work

I just submited a pull request that implements completion for dictionary variable names and another pull request that implements completion for dictionary items, even for nested dictionaries.
