commit dfdf9c21cbe7896d03da011773e636fc287d97db
Author: Jostein Kjønigsen <jostein@kjonigsen.net>
Commit: Yuan Fu <casouri@gmail.com>

    Fontification improvements in typescript-ts-mode (bug#60500)
    
    - highlight method-definitins in interfaces.
    - only highlight variable-declarations, not variables
      everywhere (consistency with other modes).
    - move highlighting of method invocations to level 4
    
    * lisp/progmodes/typescript-ts-mode.el:
    (typescript-ts-mode--font-lock-settings): Update rules.
    (typescript-ts-mode, tsx-ts-mode): Update feature list.
