[Feature Request] Add support for other mocking frameworks

[SimonMarquis]

Would you consider adding support for another popular mocking framework?
We currently have developped our own ad-hoc Lint detector to report wrong usages of mocks using the Mockk.io library.
But I think we could benefit from running this detection only once our codebase.

It could be done either with a lint config parameter, or maybe simpler by adding the relevant classes/methods in these variables:

slack-lints/slack-lint-checks/src/main/java/slack/lint/mocking/MockDetector.kt

Lines 34 to 41 in fd01ddf

	val MOCK_ANNOTATIONS = setOf("org.mockito.Mock", "org.mockito.Spy")
	val MOCK_CLASSES =
	setOf(
	"org.mockito.Mockito",
	"slack.test.mockito.MockitoHelpers",
	"slack.test.mockito.MockitoHelpersKt"
	)
	val MOCK_METHODS = setOf("mock", "spy")

For reference, I tried to build of version of our internal Detector over here:

• Create a Lint detector to warn about undesired usages of mockk mockk/mockk#1003

I'd be open to making these mock factories configurable, similar to what we do in compose lints for view model injection - https://github.com/slackhq/compose-lints/blob/main/compose-lint-checks/src/main/java/slack/lint/compose/ViewModelInjectionDetector.kt#L25-L31

@ZacSweers I started a draft PR #126 and for now I extracted the previous values as defaults.
I'm not sure what your thoughts are about this (empty defaults, vs existing mockito ones).

Also, regarding the potential tests to be added, what would make more sense here?

• Duplicate each corresponding slack-lint-checks/src/test/java/slack/lint/mocking/* tests
• Parameterizing the test suites with JUnit's Parameterized runner
• Or adding a few tests to cover most cases in a separate test class

[ZacSweers]

Keeping the defaults sounds good. I think we may also want to unify classes and methods together, i.e. "org.mockito.Mockito.mock" rather than split them.

For tests, keeping the existing defaults while added some basic extra tests to test that custom mocking factories are working I think should be enough.
