Edited olive saplings quest to allow all Harvestcraft saplings as choice rewards.

Until the market is fixed, this change allows players to access whatever Harvestcraft saplings they want without having to spend hours searching with little chance of success at finding any particular one.

This might have been better as a ticket for discussion. not just a PR. See discusssion in #quest-dev.

In short, it removes some exploration for the purpose of (even) faster food progression (and thus hearts). Which might be a negative or positive depending where you stand on this.

If there is a dev who is willing to take it on, this backport might be a much better alternative: https://github.com/GTNewHorizons/GT-New-Horizons-Modpack/issues/9665

To be clear, this is intended purely as an interim solution for acquiring Harvestcraft saplings, and is intended to be removed once the market, or a backported Farming for Blockheads, is implemented. Since that will mean adding a practical way of acquiring the saplings without excessive exploration anyway, I made this pull request as a temporary alternative.
