Fix:
Suggest an edit to update the provided command from tutor dev quickstart to tutor dev launch to configure and provision an Open edX instance.

@mphilbrick211, I managed to complete the developer Quick Start: First Open edX Pull Request. I encountered a couple of errors due to the documentation being outdated. I would like to share the updates I made to complete the Quick Start successfully (sourced for the Tutor documentation and CHANGELOG).

Kindly advise me. Should I open a new pull request or add to this existing one?
Note, some modifications require major section updates.

[apexDev37]

First, @mphilbrick211 and @feanil, thank you for the great support🌍
I raised a concern about an outdated section I encountered in the same developer Quick Start: First Open edX Pull Request.

[apexDev37]

Section: Mounting edx-platform
Noted areas of concern include:

1. The provided command tutor dev run --mount=./edx-platform lms bash to mount to a local edX checkout is deprected.
2. Bashing into the LMS container to set up is now redundant and performed by Tutor automatically on launch.
3. The steps provided can be significantly reduced to the following flow: fork, mount, and launch as specified here.

Source of information:

1. Official Tutor CHANGELOG
2. Official Tutor Documentation

Additional information:
This section required updates beyond minor "suggested edits". The updates can be observed in this feature branch.
If applicable, I can create a new pull request.

Your advice on merging the necessary update to the developer Quickstart is appreciated.
