1. Fix incorrect keyword lexing …

   For some weird reason this line is detected as a keyword line:
   
   ```
               type: :module,
   ```
   
   Though it clearly isn't. Ripper:
   
   ```
   require 'ripper'
   
   pp Ripper.lex(<<~'EOM')
     {
       type: :module,
     }
   EOM
   ```
   
   Produces:
   
   ```
   [[[1, 0], :on_lbrace, "{", BEG|LABEL],
    [[1, 1], :on_ignored_nl, "\n", BEG|LABEL],
    [[2, 0], :on_sp, "  ", BEG|LABEL],
    [[2, 2], :on_label, "type:", ARG|LABELED],
    [[2, 7], :on_sp, " ", ARG|LABELED],
    [[2, 8], :on_symbeg, ":", FNAME],
    [[2, 9], :on_kw, "module", ENDFN],
    [[2, 15], :on_comma, ",", BEG|LABEL],
    [[2, 16], :on_ignored_nl, "\n", BEG|LABEL],
    [[3, 0], :on_rbrace, "}", END],
    [[3, 1], :on_nl, "\n", BEG],
    [[4, 0], :on_const, "EOM", CMDARG]]
   ```
   
   This is the problem line:
   
   ```
    [[2, 9], :on_kw, "module", ENDFN],
   ```
   
   Digging into the IRB source code they handled this case here ruby/ruby@776759e. Based on the description I believe this may be a bug in the lexer, but I'm not sure how to validate it.
