Fix typo: controller_snapshot_removal_timeout_minuts should be controller_snapshot_removal_timeout_minutes

[coderabbitai]

Description

There is a typo in the field name controller_snapshot_removal_timeout_minuts which should be controller_snapshot_removal_timeout_minutes.

Scope

This typo appears to exist in multiple places and needs to be fixed across:

• Operator code
• CRD manifests
• Documentation
• Any other references

Approach

• Add the correctly spelled field controller_snapshot_removal_timeout_minutes
• Keep the misspelled field for backward compatibility but mark it as deprecated
• Update operator code to handle both field names during transition period
• Update documentation to use correct spelling

Context

Identified during PR #2690 which focuses on documenting current operator features.
