Use go.uber.org/mock/gomock

[owenniles]

In this PR, I’ve replaced github.com/golang/mock/gomock with go.uber.org/mock/gomock. The original repository, github.com/golang/mock, appears to be unmaintained since June 2023. Its README recommends switching to Uber's fork, which is actively maintained.

Version v0.4.0 of go.uber.org/mock is the latest release compatible with the Go version specified in our go.mod file (1.20). Upgrading beyond v0.4.0 would require us to update the go directive to a newer Go version.

@frairon @norbertklawikowski Just added one more commit to generate mocks using the pinned version of mockgen rather than the system version. This ensures that all contributors will use the same version of mockgen to generate mocks. It also means that contributors won't need a separate system installation of mockgen. All a contributor will need to do to regenerate mocks is invoke go generate.

@norbertklawikowski I'll rebase after #470 is merged to fix the failing CI?

@owenniles I ran the tests successfully locally, so I will merge :) Thanks for your work!
