Test: Validate domain config test for attrValidator

[abhishekj720]

Description: This PR introduces enhanced unit tests for attrValidator.go in the uber/cadence/common/domain package, focusing on increasing test coverage through comprehensive, table-driven tests. It covers a range of scenarios including edge cases and error conditions for domain attribute validation functions.

Why?: To improve code quality and reliability by ensuring all logical paths are tested, which helps in early detection of potential bugs and maintains high standards for the Cadence codebase.

How did you test it?: Tests were added and executed locally to verify their effectiveness. The coverage tool was used to ensure that the new tests significantly increase coverage for attrValidator.go.

Potential risks: Minimal to none, as the changes are confined to unit tests which do not affect production code directly.

Release notes: Not applicable as the changes do not impact the functionality or schema.
