This commit fixes compiling with latest CMake: google/re2@9ebe4a2

Need to create a update in this repo similar to this one: 3d104df (maybe after RE2 does next full release)?

I was going to create a PR myself but there's no proper release of RE2 with that fix in just yet so I'm creating an issue to track the problem.

Thanks

Once there's a new release of RE2 any objections updating the dependency version in this repo to the latest version? I will create a PR.

I'll check for any breaking changes. It's been over two years since RE2 was updated.

It seems @veblush is already working on updating re2. Esun, can you just use the next upcoming release please?

[xanather]

There is a new re2 release with the fix included https://github.com/google/re2/releases/tag/2024-05-01. @veblush you want me to create PR or you got it?

[veblush]

@xanather It'd be great if you can make a PR for this one.

Hi @veblush, take a look at #36558. Cheers.

Any chance this could get merged @veblush @yashykt 🤔
