[cppgraphqlgen] Fix --head for new branch/option

[wravery]

Describe the pull request

• What does your PR fix?

I'm not ready to update cppgraphqlgen to the v3.4.1 release yet because it depends on a change in pegtl which hasn't been released as v3.1.1 yet. However, installing both of those with --head should work, and right now it doesn't work for cppgraphqlgen. I renamed the default branch from master to main, and there's a new GRAPHQL_UPDATE_VERSION=OFF CMake option which the portfile needs to specify. Using that option with a prior commit will just be ignored.

• Which triplets are supported/not supported? Have you updated the CI baseline?

No, as far as I know the CI baselines should all work.

• Does your PR follow the maintainer guide?

Yes.

Could you please also bump version in CONTROL file?

Hi @wravery

Thanks for your PR.

Have you tested if ./vcpkg install cppgraphqlgen--head works fine on your local?

I tried to install on my machine, it posted the error like this:

CMake Error at CMakeLists.txt:76 (add_subdirectory):
  The source directory

    F:/tool/vcpkg/buildtrees/cppgraphqlgen/src/head/main-211b762c03.clean/PEGTL

  does not contain a CMakeLists.txt file.

It does require that you install pegtl with --head as well. Otherwise it tries to use the submodule copy of it, and that doesn't work with vcpkg.

Thanks for your response @wravery.

Have installed successfully now after install pegtl with --head.

Could you please also bump version in CONTROL file?

Since I'm not actually changing the commit, I just added -1 to the date-based version. Let me know if there's a better version scheme to handle that situation.

LGTM now, thanks.
