c++-ts-mode with latest tree-sitter-cpp grammar barfs on "virtual" |

When using latest master Emacs with latest release tree-sitter and
latest version of tree-sitter-cpp, we get an error redisplay in
redisplay complaining that the "virtual" keyword in c-ts-mode--keywords
is an invalid query. Removing "virtual" from the list in c-ts-mode.el
resolves the problem, but of course, results in the "virtual" keyword
not being fontified as a keyword.
