RenameVariables does not work on variable in EXCEPT arguments, nor WHILE limit

[gohierf]

I recently decided to enable RenameVariables transformer and noticed it missed variables in the EXPECT arguments.

BEFORE

AFTER

Code to reproduce

My Keyword
    [Arguments]  ${expected error}
    TRY
        No Operation
    EXCEPT  ${expected error}
        No Operation
    END

It does not seem to update the variables used in WHILE's limit option either.

BEFORE

My Keyword
    [Arguments]    ${my condition}    ${my limit}
    WHILE    ${my condition}    limit=${my limit}
        No Operation
    END

AFTER

My Keyword
    [Arguments]    ${my_condition}    ${my_limit}
    WHILE    ${my_condition}    limit=${my limit}
        No Operation
    END

Fixed - will be part of Robocop 6.0.
