fix: renaming standaloneDeployment variable to be consistent

[TresTristesTrigues]

This PR fixes 2 issues:

1. There was a mismatch with variable naming in the Flyte-Core chart, where standalone_deploy and standaloneDeployment were being used interchangeably
2. cluster_resource_manager could be deployed twice as part of flyteadmin and standalone

cluster_resource_manager could be deployed twice as part of flyteadmin and standalone

Do you think this is still the case with the changes you're proposing?

Thanks!

@davidmirror-ops
I am not sure if it should be possible to deploy it has both standalone and flyte-admin, I assume not.
In that case, should this line be changed to:

{{- if and (.Values.cluster_resource_manager.enabled) (.Values.cluster_resource_manager.standaloneDeployment) }}

? (in contrast to this line)

Sorry for the delays. Thank you!
