alignof operator in C is not highlighted correctly

[LeoriumDev]

I think a in alignof is not colored properly. I am using clangd extension targeting C23 in vs code.

The performance optimizations here are quite clever. Nice engineering work!

@tstellar: Looks like bot account that creates noise in notifications. See also #139346 as example.

The highlighting shown in the screenshot is not produced by clangd; I see it in vscode even with the clangd extension disabled, suggesting that it's coming from vscode's client-side highlighting.

I think the right place to file an issue for that would be https://github.com/jeff-hykin/better-cpp-syntax/.
