tests(insert): add insert tests for json, text array and integer array

[minh-hoang-trinh]

TLDR: add various tests case for the PR #5431 (rollback of #5321)

• insert tests for array of object into text array column Malformed array literal: Knex 2.4.0 regression #5430
• insert tests for array of integer into integer array column Inserting into PostgreSQL array columns are broken on master branch #5365
• insert tests for array of string into text array column Inserting into PostgreSQL array columns are broken on master branch #5365
• insert tests for json object into jsonb column

the PR #5431 by @caseywebdev should be merged first

A little bit more explanation:

#5365 : user want to insert array of string into text array column, or array of integer into integer array column, which is valid and should be inserted, but the PR #5321 merged sometime ago break it (it will always stringify the array to json string)

@kibertoad At first I thought I can add a check for Array containing at least one plainObject with my previous PR #5444, but turn out it will not solve the #5430, my previous changes will need user to input a valid array of string into text array column

#5430 : user want to insert array of object into text array column (worked in previous version of knex). the PR #5321 break it (it will always stringify the array of object to json string)
