Feat: support for laravel preview environment (feature testing)

[aagjalpankaj]

serversideup/docker-php image can be used efficiently to test one feature at a time if we allow migrate:fresh --seed.

e.g. We have 3 environments:

• Production (for the tag generated from main branch)
• Staging (for main branch)
• Testing (for feature branches)

We use Testing environment to deploy one feature at a time. But it creates incompatibility b/w the feature and database state. Because of that, we can't test features efficiently on Testing environment. Also, sometimes deployment fails and we need to reset the database manually.
