Install Joomla with non-standard db_port

[muhme]

This is one puzzle piece for joomla/joomla-cms#43902 – Installing Joomla with non-standard database port.

In the Joomla System Tests this PR is only working together with joomla/joomla-cms#43968.

With currently (August 2024) Joomla Web Installer it is only working for MariaDB and MySQL. It is not working for PostgreSQL.

Isolated only testable that it does not harm.

You could see this PR is already used as hack in Joomla Branches Tester. There you can see it working in scripts/cypress.sh 44 local and running in the Installation.cy.js step. If you revert the changes in file branch_44/node_modules/joomla-cypress/src/joomla.js the Joomla Web Installer fails with:

Could not connect to the database. Connector returned error message: No such file or directory

I disagree. This PR is necessary because it translates the db_host and db_port entries from the cypress.config.mjs file into a host:port format, which is then inserted into the 'Enter the host name' field in the Joomla Web Installer. The Web Installer only has a single host field and does not have a dedicated port number field. On the other hand, in the Cypress System Tests configuration, we are working with the host and port separated for the database drivers.
