Trino: Quote reserved keywords in type signatures

[ljfgem]

This PR is to quote the reserved keywords which might appear as field names in the type signatures, i.e. row(key varchar, values varchar) -> row(key varchar, "values" varchar), if they are not quoted, io.trino.sql.analyzer.TypeSignatureTranslator.parseTypeSignature will throw exception like:

io.trino.sql.parser.ParsingException: line 1:24: mismatched input 'values'. Expecting: <identifier>, <type>

Tests:

1. Unit tests, which will fail without quoting
2. ./gradlew clean build
