FINERACT-2557: Update Quick Start to focus on PostgreSQL and remove MySQL-specific database commands

[tiagosune]

Description

FINERACT-2557

This PR updates the Quick Start section to align with FSIP-9 by focusing on PostgreSQL as the primary supported database.

The previous instructions included database creation commands that only work with MariaDB/MySQL (createDB). Since PostgreSQL is now the recommended database, those commands were removed to avoid confusion.

The Quick Start section now:

• Assumes PostgreSQL is properly configured
• References the detailed database setup section for further instructions

Additionally, this change keeps the Quick Start simple and avoids including commands that may not work out-of-the-box for PostgreSQL.

Please let me know if there's a preferred way to include PostgreSQL-specific setup instructions here.

Following up on the previous feedback, this PR updates the Quick Start section to focus on PostgreSQL and removes database creation commands that were specific to MariaDB/MySQL.

Let me know if we should include PostgreSQL-specific setup commands here once the recommended approach is clarified.

Thanks for the ping!

I’m currently updating the PR to use the createPGDB task as suggested and testing it locally. I’ll push the changes shortly.

I updated the Quick Start section to use the createPGDB task as suggested.

I also tested it locally and confirmed that it works when PostgreSQL is properly configured. In particular:

• the PostgreSQL user and password must be set (e.g. root/postgres as used in CI)
• an initial database (e.g. "root") must exist for the connection

I added a note in the documentation to clarify these requirements and updated the commit accordingly.

Please let me know if you'd like me to simplify or expand the setup instructions further.

Will you please rebase your branch on top of develop (and force push again) before I merge this? It's been quite a few merges since this PR started, so it'll be must cleaner to merge if you rebase first.

[meonkeys]

please rebase on develop latest (b26571b as of right now, and it probably won't move in the next few hours)

Done! I’ve rebased the branch on top of the latest develop and force-pushed the changes.

Please let me know if everything looks good now.
