Expand ${VAR} references in YAML config files using os.ExpandEnv

Applied to all three YAML parsing paths: LoadFile (viper),
ParseStreamConfig (yaml.Unmarshal), and ParseTransformerConfig.
Fixes xataio#383

Summary
Adds
os.ExpandEnvsupport to YAML config parsing so users can reference environment variables like${DB_PASSWORD}in config files instead of hardcoding secrets.Applied to all three YAML-backed parsing paths:
LoadFile(viper): reads file manually, expands env vars, feeds toviper.ReadConfigParseStreamConfig(yaml.Unmarshal): expands before the case-sensitive YAML parseParseTransformerConfig: expands before transformation rule parsingAlso handles the transformer rules merge path (
PGSTREAM_TRANSFORMER_RULES_FILE).Example config:
