Test failure: com.linecorp.armeria.server.ServerBuilderTest.contextHook()

[my4-dev]

Motivation:

#5769

Modifications:

• Added tearDown method with @AfterEach in order to reset each count variables used in tests

When executing this test in my local env, this test succeeded and I wasn't sure why this test failure was caused.
But, after adding this tearDown method, we will be able to avoid inappropriate variables staying in cnt variables.

Result:

• Closes Test failure: com.linecorp.armeria.server.ServerBuilderTest.contextHook() #5769
• Test failure: com.linecorp.armeria.server.ServerBuilderTest.contextHook() will be resolved.

Regardless of whether this fixes the actual flakiness, I agree that shared variables should be reset to avoid dependencies between tests. Thanks 👍
