bug#60882: 30.0.50; enabling c-ts-mode in header files

[Felix]

If i follow the steps described in Yuan's tree-sitter starter guide:

(add-to-list 'major-mode-remap-alist
	     '(c-mode . c-ts-mode)
	     '(c++-mode . c++-ts-mode))

c-ts-mode is enabled if i open .c files, but for .h files it's still
c-mode.
I checked this with the -Q command line option.
Thanks

You need to also remap c-or-c++-mode to c-or-c++-ts-mode, which is used
for headers (because C and C++ both can use .h for header files).
