feat: Add feature view versioning support to Snowflake online store by Abhishek8108 · Pull Request #6380 · feast-dev/feast

Introduces `_snowflake_table_name()` helper that appends a `_v{N}` suffix
when `enable_online_feature_view_versioning` is set, routing write_batch,
online_read, update, and teardown to the correct versioned transient table.
Registers SnowflakeOnlineStore in the supported-types list so versioned reads
do not raise VersionedOnlineReadNotSupported. Unit tests follow the same
pattern as the DynamoDB and Redis versioning test suites.

Closes feast-dev#6167
