wdl-grammar-v0.5.0

Fixed

• Fixed parsing of workflow conditional statements to require parenthesis
  surrounding the expression (#94).
• Fixed attaching trivia to the CST before starting a node (#91).
• Fixed the CST for an unparsable file (i.e. one without a supported version)
  to contain trivia before the version statement and correct spans for the
  unparsed token (#89).
• Fixed last trivia in the file attaching as a child to the last node in the
  file instead of as a child of the root (#89).
• Fixed diagnostics around encountering string member names in struct literals
  (#87).
• Fixed diagnostic label spans that point at strings to include the entire span
  of the string (#86).
• Fixed trivia in the CST so that it appears at consistent locations; also
  fixed the parser diagnostics to be ordered by the start of the primary label
  (#85).
• Fixed a missing delimiter diagnostic to include a label for where the parser
  thinks the missing delimiter might go (#84).
