fix: generate command not found with core 18.1.0

[strophy]

Issue being fixed or feature implemented

dash-cli generate returns error message: Method not found with 18.1.x builds of Dash Core

What was done?

Replace generate with generatetoaddress, this command is backwards compatible so older versions of core should still work when runnings tasks that require blocks to be created.

How Has This Been Tested?

Tested while deploying a devnet with the latest core build on devnet-jammy, a small devnet to test updating the Ubuntu base image.
