displayColour syntax not checked well and can give false error messages

New PR above

The PR above current does not include test cases yet.
@syedahmed1674 Will Push Test Cases later and will make a comment again

PR Title

Support the implementation of Display Color assignment with Parenthesis.

Example

displayColor = "red" <-- This does not work originally

PR Description

It was originally stated by @syedahmed1674 that by implementing the following into UmpleInternaalParser_CodeLayout + _CodeClass:

theColor = theColor.replace("=", ""); // Remove all '=' characters
theColor = theColor.replace(""", ""); // Remove all '"' characters

It would fix the issue by replacing any parsed values for the Coloring to remove the assignment sign and the quotation sign, It was later found that it does not pass through Grammar Test Cases and raises error 1502.

It was later discovered by @AxelTWC debugging that by removing the code:

      if(!theColor.startsWith("\"")) theColor= "\""+theColor;
      if(!theColor.endsWith("\"")) theColor= theColor+"\"";

It solves the issue where there will not be an extra " whenever having a quotation valued assignment
(Originally Debugging Gives " "red" by doing displayColor = "red" | It should fix the issue now)
A full build was ran and passes all previous cases in prior to making sure this works perfectly.

@syedahmed1674 Will Push Test Cases Specifically for this PR #2060 /Issue #2056
