Include string in Pythia6Declarations.h

[Teemperor]

We use std::string in this header, so we also need to include
string to make this file parsable on its own.

[Teemperor]

Part of the work going on regarding the C++ modules migration of CMSSW (tracked as issue #15248). This PR is not meant to refactor things, but just to make these headers compile.

There are some workflows for which there are errors in the baseline:
10824.0 step 5
The results for the comparisons for these workflows could be incomplete
This means most likely that the IB is having errors in the relvals.The error does NOT come from this pull request
