Drink 0.8.7

[pmikolajczyk41]

Fixes #107

1. Revert Update cargo-contract crate versions #91 (go back to [email protected] and contract_*@3.2.0)
2. Port Accessing emitted events #92 feature over these reversion
3. Bump rust to 1.74

If common-amm and ink-wrapper works well with 0.8.7, then 0.8.6 and 0.8.5 will be yanked

Thanks for doing this.

As for "git hygienic" - can you try with get revert first next time? I understand that it might require more work "afterwards" (ie in the "fix the revert commit" commit) but it's cleaner what the flow/reasoning was. I think.
