Update the injector to use rapidity instead of eta

[BongHwi]

We're suspecting the strange injection results may come from the injection scheme we're using.

So we would like to try to produce some injected MCs from the local grid submission with the rapidity property.

Accordingly, the injection script has been introduced and updated all related files.

Crash seems unrelated to this PR. @ktf have you seen this error somewhere else recently?

[ktf]

No, I have not seen it. Also keep in mind that the new version of ROOT is not merged, so effectively nothing changed there.

[jackal1-66]

This is quite curious. I tested the PR on lxplus and I don't get the error, however I fet other failures on three configurations:

Could you have a look @BongHwi ?
@ktf the errors are even more confusing now in the CI:

[BongHwi]

Thanks a lot @jackal1-66 for checking the detailed errors.
I overlooked it since I tested the script only with the default injector.
Since we don't have a plan to test the triggered-production now, I removed them.

[jackal1-66]

Problem is actually somewhere else: #2174
This PR should fix the issue and your tests should be successful. The problem is that at building time the include paths are not set so you're not able to include the nlohmann_json header file.

[BongHwi]

Thanks @jackal1-66 for checking the error!
Let's re-test this PR once the PR is merged.

[jackal1-66]

CI is now green, it will be merged when someone from LF approves it

[BongHwi]

Great, I've contacted PAG convener, but actually I used to merge it before without other approval I remember...
