fix: use eq method for ne for SnowflakeObject

[AstreaTSS]

This makes sure objects without an "id" attribute are still correctly compared.

Description

Trying to compare a SnowflakeObject to something else that didn't have an id attribute via != would always error out. This PR fixes that by making __ne__ use __eq__.

Changes

• Make SnowflakeObject.__ne__ return the opposite of __eq__ instead of using custom logic. Honestly, I think you could just remove it altogether, but this was safer.

Test Scenario(s)

Just use SnowflakeObject(SOME_ID) != None.
