93b9800fec588fc0c258e754405db1e9f89cfb81 scripted-diff: Rename overloaded int GetArg to GetIntArg (Russell Yanofsky)
Pull request description:
This is meant to improve readability of code and remove guesswork needed to determine argument types and migrate to [typed arguments (#22978)](https://github.com/bitcoin/bitcoin/issues/22978) by having distinctly named `GetArg` `GetArgs` `GetBoolArg` and `GetIntArg` methods.

This commit was originally part of #22766 and had some review discussion there. But it was [wisely suggested](https://github.com/bitcoin/bitcoin/pull/22766#issuecomment-910001542) to be split off to make that PR smaller.
