Deploy DonationMiner on another networks

[vibern0]

Is your feature request related to a problem? Please describe.

Currently, the impact farming is deployed only on Celo network. This limit us to the Celo users and cStables circulating.

Describe the solution you'd like

We should be able to attract capital (donations) from other networks.

Additional context

Currently, 40% of the total PACT supply is allocated to the impact farming on Celo. It should still be 40%, but split across chains.
The goal is to deploy only the bare minimum to get the donations rewards working on another chains.
