fix: Operator chart blocking access to metrics endpoint

[solidDoWant]

The metrics endpoint only listens on localhost, making it impossible for metrics scrapers (prometheus, victoriametrics) to reach. This PR removes the bind-address arguments (the health probe argument is redundant as it's set to the program's default value), which will allow scrapers to reach the pods.

https://github.com/dragonflydb/dragonfly-operator/pull/281 is probably preferable to this PR, but there have been no reviews from maintainers. I'm hoping that filing a different approach to the issue will get somebody's attention.
