Developer Workflow

[Ron-Zarbyte]

Refer to: FOSSBilling/FOSSBilling#1583

This improves workflow documentation from the perspective of a developer new to FOSSBilling. Two options are documented:

1. Remote Installation (for cpanel, plesk, apache, nginx, etc)
2. Local installation with Docker (using locally built images versus the fossbilling docker repo)

I feel these updates accomplish the goal of clarifying new developer workflow, but I am open to making more improvements where needed.

The documentation does refer to a specific install folder handling with enabling debug mode. That behavior does not exist yet, and is something I submit a pull request for. Refer to: FOSSBilling/FOSSBilling#1692

Looks like a pretty decent start. I pushed to your branch to add formatting to the shell codeblocks and to include info on PHPStan.

Docker info looks to be complete and I'm happy with that and I'm indifferent about the remote installation page.

In the same subject of all of this, we also have a (very basic) Building FOSSBilling page which should probably be improved and then moved into the developer workflow.

It would also be nice to get those steps updated to include info on the new translation releases and how to set those up, but that's really an optional step & only matters if someone wants a dev instance that has all of the correct translations with their completion % available inside of FOSSBilling

Agreed on those points. I'll loop back to this after the installer and get those additions in.
