Handle typescript ts grammar breaking change for function_expression
Starting from version 0.20.4 of the typescript/tsx grammar, "function" becomes "function_expression". The right expression is used depending on the grammar version. * lisp/progmodes/typescript-ts-mode.el (tsx-ts-mode--font-lock-compatibility-function-expression): New function (bug#69024). (typescript-ts-mode--font-lock-settings): Use it. Copyright-paperwork-exempt: yes
