Fix: QueryBuilder's TextConstraint for Postgres

[Zanzofily]

Description

When a table name or column name contains uppercase letters, both table name and column name gets wrapped between double quotes inside any TextContraint operator.

for example: Flight table name with code field name becomes "Flight.code" which results in column not found error. Instead, it should be "Flight".code, and if column name contains uppercase letters, it should be "Flight"."Code".

Example error: Undefined column: 7 ERROR: column "Flight.code" does not exist LINE 1: ...count(*) as aggregate from "Flight" where (lower("Flight.c... ^ (Connection: pgsql, SQL: select count(*) as aggregate from "Flight" where (lower("Flight.code"::text)::text like search_string%))

It might not be very common when it comes to Laravel naming conventions, but I encountered this issue while building a dashboard for an app that was initially developed with Next.js and prisma, where this naming convention is common.

Functional changes

• Code style has been fixed by running the composer cs command.
• Changes have been tested to not break existing functionality.
• Documentation is up-to-date.
