Use CircuitBreaker.tryRequest() instead of deprecated canRequest() in doc and test

[cirusthenter]

Motivation:

Fix docs and tests to use a new method CircuitBreaker.tryRequest() instead of deprecated CircuitBreaker.canRequest().

Modifications:

• Fixed a line in site/src/pages/docs/client-circuit-breaker.mdx to use a new method CircuitBreaker.tryRequest() instead of deprecated CircuitBreaker.canRequest().
• Fixed core/src/test/java/com/linecorp/armeria/client/circuitbreaker/NonBlockingCircuitBreakerTest.java to use a new method CircuitBreaker.tryRequest() instead of deprecated CircuitBreaker.canRequest().

Result:

• https://armeria.dev/docs/client-circuit-breaker/ will be updated to show an example of using a new method CircuitBreaker.tryRequest().

Thanks a lot, @cirusthenter!
I noticed that the canRequest method is still being used in NonBlockingCircuitBreakerTest.
Could you please fix that as well?

[cirusthenter]

Thanks for your review. Fixed NonBlockingCircuitBreakerTest as well!
