Revert pulling zlib from custom fork

[GeckoEidechse]

Reverts #650 which was done due to builds failing due to madler/zlib@2e3d86c

[GeckoEidechse]

If CI passes, this should be good to merge

EDIT: RIP

@ASpoonPlaysGames I assumed it would just pull the newest zlib version but evidently that's not the case? Or is the upstream fix not working for us?

[ASpoonPlaysGames]

It fetches the master branch, the fix is only on develop right now

[GeckoEidechse]

Yeah so develop branch works, don't think we should use that though so best to wait until merged into master ig ^^

The fix for the issue still wasn't ported to master as of today.

One year later, situation has not changed: v1.3.1 still is the latest zlib release. 😢
